SM1ネジ付き変換アダプタ

このページでは、当社のSM1ネジ付きのネジ変換アダプタの全製品をご紹介しています。アダプタは、内ネジと外ネジの両方が付いたタイプ、および内ネジまたは外ネジが各2つ付いたタイプをご用意しています。

顕微鏡対物レンズに使用する際は、真鍮製の顕微鏡対物レンズ用ネジアダプタの使用をお勧めします。こちらのアダプタには縁が付いているので、顕微鏡対物レンズをマウントに深くねじ込み過ぎるのを防ぎます。また、真鍮はアルミニウムよりも固いため、対物レンズのネジに対する応力もかかりにくく損傷を防ぐことができます。

SM1ネジ付き変換アダプタは、当社の光学部品用ネジ付きアダプタのラインナップの一部です。全ラインナップは、ネジ変換アダプタのセレクションガイドをご参照ください。

断熱性検証

ページ下部に掲載されている低熱伝導性アダプタ(SM1A4TS、SM1A9TS、SM1A3TSならびにSM1A10TS)の断熱性を従来のアルミニウム製アダプタと比較する実験を行いました。 実験では、アルミニウム製アダプタと低熱伝導性の黒色Delrin®*製アダプタを使用して、それぞれ2本のレンズチューブを接続させました。 それからレンズチューブの外面に取り付けた箔状発熱素子でレンズチューブを外部から60 oCまで加熱しました。

加熱と同時に各システムの加熱されているレンズチューブならびに加熱されていないレンズチューブのそれぞれの温度を30秒毎に記録しました。 測定結果は右のプロット図に示されています。 グラフにより、2本のレンズチューブを接続する際に低熱伝導性アダプタを使用した方が、アルミニウム製アダプタよりも熱伝導がはるかに低いことが分かります。

ネジ仕様

下記はネジの概要についての説明です。仕様や寸法の詳細については、市販のMachinery's Handbook等をご参照ください。

ネジ山の名称
ネジ山は頂点(crest)、斜面(flank)、谷(root)の3つが繰り返されることで構成されています(右図参照)。特殊な場合を除き、ネジ山は、頂点または谷の中心に垂直な線を描いたとき、両側が対称的で、同じ角度で傾斜しています。隣り合うネジ山の間の距離はネジピッチと呼ばれます。フランク角とは、ネジ軸に対して垂直な線と斜面がなす角度と定義します。別途特記のない限り、ネジ山の斜面角度は30°なので、斜面と斜面の間の角度は合計で60°となります。それぞれの名称は右の図で示されています。

ネジの外径はネジ山の頂点の径、内径はネジの谷の径となります。ほとんどのネジでは頂点や谷の先端が鋭点ではないため、外径や内径の定義には頂点や谷を丸めた値が含まれています。ピッチ径は、外径と内径のおおよその中間値となります。 

Thread Form
Thread Formはネジの特長を定義しています。世界の多くで使用されているのはISOミリネジで、国際単位系で測定されています。またアメリカではインチ単位で測定されたユニファイネジが一般的です。ユニファイネジには様々な形状がありますが、UN規格は谷の輪郭が平ら、UNR規格では丸くなります。UNやUNRに文字を追加することによりネジ山の形状が詳細に説明されます。例えば谷の輪郭が平ら(UN規格)で極細目(extremely fine)のネジはUNEFネジとなります。またユニファイネジ規格で特殊なネジはUNSネジとなります。 

Thread Series
ほとんどのネジはThread Seriesで識別されます。Thread Seriesは外径とネジ山の密度で示されます。ネジ山の密度はミリネジではネジピッチ、ユニファイネジではThreads per Inch(TPI)で規定されています。ユニファイネジの場合、1/4"-20キャップスクリュのバレルは直径が1/4インチ、ピッチは20 TPIと表されます。ミリ規格のM4 x 0.7キャップスクリュのバレルは直径が4 mm、ピッチが0.7 mmです。M4 x 0.7はよくM4に省略されています。

  • 公差等級が上がると公差が大きくなります。通常の長さのはめあいでは下線が引いてある等級が使用されます。

Thread Class
ネジ山の公差と許容差は、ネジのクラス(thread class)によって示されます。ユニファイネジは英数字で識別されます。数字は1から3まであり、大きいほど公差が厳しくなります。また、Aは外ネジ、Bは内ネジを示しています。

ミリネジは、数字の3から9までの公差等級と、eからhまでの公差位置で公差が決まります。等級がそのまま公差の度合を示しており、数字が小さいほど公差が厳しくなります。位置はピッチ径からの公差の距離を示しています。またアルファベットの大文字は内ネジ、小文字は外ネジです。 

Machinery's Handbook, 29th Edition, p. 1885より(和訳):「公差域クラスは、最初にピッチ径の等級と位置が記述され、次に外ネジの場合は外径のの等級と位置、内ネジの場合は内径の等級と位置が記述されます。よって外ネジの場合は4g6g、内ネジの場合5H6Hというような表記となります。2つの等級と位置が同じの場合は、繰り返す必要がないため、4g4gの場合は4g、5H5Hの場合は5Hとなります。」

当社のSMシリーズ規格
SMシリーズ規格は、当社のレンズチューブやケージシステム部品に使用されています。下表はご用途に合ったコンポーネントを機械加工する際にご参照ください。多くのSMシリーズネジ規格は特殊ネジ(UNSネジ)で、側面角度は30°、ネジクラスは2A および2Bになっております。ただしSM30シリーズネジはミリネジで、側面角度は30°、公差は6H/6gです。当社ではCマウントやRMSネジ付きの製品もご用意しております。ネジ規格は下記をご覧ください。なお、他社製品は公差が下記ネジと異なる場合がありますのでご注意ください。こちらに掲載されていないネジの規格については当社までお問い合わせください。

Thank you for contacting Thorlabs. SM1A27 is in fact not missing from the table you have linked. You just need to click on the blue "i" icon under SM1 external threads and M26 x 0.706 internal threads (thus matching the threads on the SM1A27). Clicking on this will open up a window containing the information and specifications regarding SM1A27.

Is the M35 x 0.5 thread (component SM1A57) compatible with M35.5 x 0.5 threads (such as the filter threads on camera lens MVL12M1)? These threads do not appear to be compatible based on the thread spec's, but maybe you know better than I do. If they are not compatible, it would be helpful to have an M35.5 x 0.5 adapter to SM1 or SM2 threads. Many machine vision camera lenses have M35.5 x 0.5 filter threads (Thorlabs sells some of these lenses), and I would like to adapt this filter thread to SM1 or SM2 threads to connect to other optical systems.
jpolaris  (posted 2023-06-15 03:03:44.0)
Thank you for contacting Thorlabs. We do not recommend using M35 x 0.5 thread adapters such as SM1A57 on components with M35.5 x 0.5 threads such as those on MVL12M1. While the threads may match for the first few rotations, there would be a risk of damaging both components. Metal shavings may also be left behind if this is attempted. This will be brought up with our design team.

What is the bore size shall I define for SM1A1 threads, if I want to run the SM1A1 tap. Thanks Nadir
YLohia  (posted 2021-03-12 04:02:20.0)
Hello Nadir, what thread are you specifically referring to? Internal SM1 or external SM05? The SM1A1 is an adapter -- it is not a single thread type or a tap.
Hong-Ruei Chen  (posted 2021-03-08 23:08:36.607)
Hi, Could you provide the specification of the SM series thread such as the thread pitch, thread angle, and manufacturing tolerance, etc?
YLohia  (posted 2021-03-09 11:20:26.0)
Hello, please see the "Threading Specs" tab on this page. The tolerances depend on if the threads are Class 2 or Class 3, but are based on the Unified Series Thread Standards. For example, our SM05 external threads are listed as "External Thread, 0.535"-40.0, UNS-2A". The pitch is 40 TPI while the tolerances are governed by the UNS-2A class. The thread angle is 60 degrees for all of our UNS threads (including SM-series threads).

Is SM30 = c-mount thread? If so, why on earth don't you say so? You have other adapters labelled as c-mount. It would have saved me a lot of time if you'd mentioned it anywhere!
YLohia  (posted 2020-12-15 02:39:48.0)
Thank you for contacting Thorlabs. The SM30 thread is specified as M30.5 x 0.5 thread while the C-mount thread is 1.00"-32. Please refer to the Specs tab. These are not the same type and are not cross-compatible.

Can you help me? I’ve got a very similar retaining ring on an automotive mirror, being plastic with extremely narrow slots. Nothing I’ve tried will budge the ring. Can you point me to a tool that will fit something like this? At the moment I don’t have the specific diameter of the ring, but if there’s hope, I’ll measure!
llamb  (posted 2020-07-29 04:15:33.0)
Hello, thank you for contacting Thorlabs. If your retaining ring appears similar to our SM1A3 adapter, then our SPW801 adjustable spanner wrench is our best option for a tool to help remove the retaining ring.
万和 李  (posted 2020-06-12 22:17:02.917)
The surface of SM1A9 is designed only for hand operation which can adapt to most conditions. But when it is screwed too tightly, we need wrench like SPW502 to help this, while there is no place for SPW502. So I am wondering if you can reconsider this problem.
llamb  (posted 2020-06-15 03:42:32.0)
Thank you for your feedback. We will consider this product suggestion. For the time being, you can also consider our TGP1 soft-jaw pliers to better grip the SM1A9 or your mating parts.

We are interested in mounting RMS-thread objectives to the SM1 system. This almost works for us, but we are not interested in thermal isolation but do care about stability. A similar part made of metal (something along the lines of M32RMSS) would be much better.

Hello, we offer the SM1A3 on this page, which is made of anodized aluminum and doesn't have any special thermal isolation features.

Hello, thank you for contacting Thorlabs. Yes, we are able to offer custom thread adapters, but we would need you to provide a mating piece we can use as a part of the inspection and quality control process. I will reach out to you directly about your application.

This adapter could be used to mount one 1" or 25mm diameter filter on a Kowa LM50JCM camera but the internal thread is not deep enough (only 3.3mm) for both a filter and a threaded retaining ring, I had to glue the filter to the adapter. A deeper internal thread, 7mm depth (2mm for the ring and 5mm for one or two filters)would be useful for similar applications. Thanks and best regards. Luciano Olivo Ergolines LAB S.r.l.

Hello, Luciano. Thank you for your feedback. SM1A36 (ext M27x0.5 to in SM1) could be used with a short lens tube in order to provide the needed internal thread. For example SM1L03 has 7.6mm of thread depth. If you don't want to glue optics in the future, this may be helpful in your application.

Hi, I would like to adapt line scanning cameras with large 16K sensors for machine vision that use M95x1.0 threads with Thorlabs SM2/SM3 tubing and caging system. Is this in Thorlabs' plan to develop adapters with M95x1.0 threads?
jlow  (posted 2015-11-20 10:08:40.0)
Tyler Morgus: Thank you for the adapter request. Thorlabs can add this adapter to our product line. I will contact you to get the details on the internal/external threading combination that you need. Tyler, Thorlabs Optomechanics Group

Can't open part document (.sldprt) for SM1A39 with SolidWorks version 11.9.0.0. I get a "Cannot Open... Future Version" error message. Other part documents open without problem. Could you please make SM1A39-Solidworks.sldprt compatible with older versions, like almost all other Thorlabs parts? Thanks.
jlow  (posted 2014-11-06 01:52:14.0)
Response from Jeremy at Thorlabs: SolidWorks do not allow saving for a previous version. However, you should be able to download the STEP file and open that in your current version of SolidWorks.

Dear Sir or Madama, do you sell adapters to mount a Nikon objective (http://objectives.nikoninstruments.com/compare.php?c[]=81) to a Zeiss LSM 7MP 2-photon-microscope? Thank you very much, Severin Filser
pbui  (posted 2013-12-12 03:38:51.0)
Response from Phong at Thorlabs: The N40X-NIR Nikon objective has M25 x 0.75 external threads while your Zeiss microscope has M27 x 0.75 internal threads. We can manufacture a custom thread adapter for you and will contact you to discuss this further.
michaelorger  (posted 2013-10-15 02:40:10.923)
I am wondering how easy it would be for you to make an M34x1 (internal) to SM2 (internal or external) adaptor?
cdaly  (posted 2013-10-17 14:54:00.0)
Response from Chris at Thorlabs: Thank you for your inquiry. We may be able to provide this one for you as a custom. We do already make adapters with use each one of these threads currently. I will contact you directly to discuss this further.
user  (posted 2013-09-05 11:16:34.873)
It would be useful to have an adapter to convert external SM1 thread to external SM05 thread.
cdaly  (posted 2013-09-11 16:02:00.0)
Response From Chris at Thorlabs: Thank you for your feedback. Our adapter SM1A1 has internal SM1 threads with external SM05 threads. If you would like to mate two components which have both external SM1 and SM05 threads, the SM1A1 adapter can be used with an SM05T1 to provide the necessary threading. If you would like the adapter to have external threading on both sides in order to mate two internally threaded components, this can be done by using the SM1A1 with the SM1T2 lens tube coupler.
tony.hainsworth  (posted 2013-03-07 15:57:28.31)
Hi, I am looking for a part similar to the SM1A9, but with both camera and SM1 tube threads external. We have actually had and used two parts just like this but need more now. I am sure we got them bundled with the CMOS cameras we bought from you but I just cannot find this part listed separately. Tony
cdaly  (posted 2013-03-07 09:54:00.0)
Response from Chris at Thorlabs: Thank you for your feedback. We do not have a single adapter which has external threads for both C-Mount and SM1, but if you thread an SM1T2 lens tube coupler into the SM1A9 adapter, you can create the desired adapter.
cdaly  (posted 2012-11-27 18:25:00.0)
Response from Chris at Thorlabs: Thank you for using our feedback feature. At the moment, we do not currently have M28 thread adapters, but we are always expanding our line of products. I have submitted your request within our internal forums and it will be considered for release by our design engineers.
dongyoung.kim  (posted 2012-11-21 20:03:00.523)
Do you happen to have M28 to C-mount adopter in the future? I know it is not a common thread (M28), but some ZEISS part use M28 threads and I really need it... Thank you!
jlow  (posted 2012-11-06 15:38:00.0)
Response from Jeremy at Thorlabs: We do not currently have an adapter for M55 thread. We will get in contact with you directly to discuss about this further.
jrestrep  (posted 2012-10-24 16:27:08.64)
Hello, this is more of a question. Are there any SM2 external / M55 internal adapters?. Thanks.

A response from Tyler at Thorlabs: I looked at all the SM1A25 drawing files and they appear to be correct. Can you contact us with more information about the problem that you experienced. As a double check, the design engineer is looking at the files. If they find a mistake it will be fixed and updated on our server by tomorrow morning. Thank you for helping us improve the quality of our website.

The solidworks file for SM1A25 is not correct, or the part number is not correct.

despinosa  (posted 2011-10-04 10:59:16.0)
The table highlights (for determining which style of mount) on this page are a pretty subtle variation in brightness- might make it a little more obvious.

Response from Javier at Thorlabs to halvorsen: Thank you very much for your feedback. We will consider the possibility of adding more thread depth to the M25x0.75 side of the SM1A12 adapter. I will contact you directly to discuss your requirements.
halvorsen  (posted 2011-08-03 09:25:00.0)
Id just like to comment on the SM1A12. It would be nice if you could increase the length of the M25 threading, since Nikon objectives do not seat properly. I have to have the machine shop here modify these, which is a pain.
jjurado  (posted 2011-07-08 10:31:00.0)
Response from Javier at Thorlabs to ajh: Thank you very much for your feedback! We will look into offering M27x0.5 adapters for use with our C-Mount DCC/DCU cameras and SM1-threaded components.I will contact you directly to keep you updated of the status of this project.
ajh  (posted 2011-07-07 16:32:31.0)
Please consider adding adapters to this range to cover more of the filter threads used by your C-mount camera lenses, e.g. M27 x 0.5 which is used by a number of the Navitar lenses. Adaptors between these threads and SM1 (at least) would be useful for integrating cameras into lens tube and cage mount based optical systems. Your DCU and DCC cameras are small and light enough to be mounted via the lens in this way, and it can often be convenient to do so.
Buki at Thorlabs  (posted 2011-01-26 13:57:38.0)
Thank you for your feedback. We have added the STEP file for the SM1A2.

In response to acables request, we have added two links to the couplers page on this page (one in the overview tab and one in the first subgroup). We have also added a link to the couplers page under the related items link. Since the couplers page is quite extensive itself (i.e. 3 subgroups), it did not seem advisable to just add those products to this page, as it would make the page quite long. Thank you for taking the time to help us improve our web pages. We hope that these new links make it easier for you to find the couplers the next time you visit our site.
acable  (posted 2007-12-12 10:12:00.0)
Please consider having the Lens Tube Couplers added to this page, ive looked for these a couple of time and always come back to this page to look for them.
