    (モータ付き製品有り)

ゴニオメータおよびゴニオメーターステージは、小さな角度範囲内で空中にある固定ポイントを中心に物体を精密に回転させるために使われる機器です。ゴニオメータはリニアステージに似ていますが、線形運動ではなくステージの取付け面上の固定ポイントを中心に部分的に回転します。当社のゴニオメータ製品には2つのシリーズがありますが、回転ポイントから取付け面までの距離が異なる2種類のゴニオメータがXY構成で積み重ねられて、同じポイントで回転できるように設計されています。当社のゴニオメータでは、小型GNシリーズでバックラッシュのない親ネジを、大型GNLシリーズでは上部プレートの角度位置決め用 に精密マイクロメータをそれぞれ使用しています。

当社のゴニオメータは、回転ポイントを中心に全回転角度にわたり真の回転運動を行ないます(右写真参照)。コンパクトで積重ね可能な設計により、回転ポイントの位置を合わせてゴニオメーターステージを別のゴニオメーターステージの上部プレートに固定することができます。GNシリーズでは、GN05/Mは GN1/Mの上に取付け可能で、GNLシリーズでは、GNL10/M は GNL18/Mの上に取り付けられます。 この2軸ステージセットは、単品(それぞれGN2/MとGNL20/M)としてお買い求めいただけます。

高精度なアリ溝とバックラッシュのない親ネジ、バーニヤ目盛により精密で再現性の高い位置決めが可能です。側面に取り付けられた止めネジ(セットスクリュ)で位置を固定できます。

GNシリーズのゴニオメータには、取付け用に#2-56タップ穴が4つ、M2.5タップ穴が4つ、M3タップ穴が8つあります。このシリーズはベースプレートのM4タップ穴からポストに取り付けるか、M3スロット付き取付け穴を使ってMS12B/Mに取り付け可能です。

一方、GNLシリーズのゴニオメータには、取付け用にM2.5タップ穴が12、M4タップ穴が16あります。取付け穴の位置については、下記または「仕様」タブをご参照ください。当社のクランプアームPM3/MPM4/Mには、M4ネジが付いているので、殆どのゴニオメータに装着することができます。このシリーズは、ベースプレートのM6スロット穴を利用して、M6タップ穴の付いた標準のブレッドボードおよびミニシリーズブレッドボードに取り付けが可能です。

: ゴニオメータに部品を取り付ける前に、型番横にある赤いアイコン (docs icon) の資料をご確認ください。取付け穴のタップ深さを超える取付具の使用はステージの損傷につながる場合があります。

なお、ゴニオメータからベースプレートを取り外すと、精密に調整されたステージの精度が低下し、再校正や再調整が必要となりますので推奨しません。

can GN2 be divided into two separate stages? thank you
mmcclure  (posted 2018-09-11 01:45:45.0)
Hello, thank you for contacting Thorlabs. The stages comprising the GN2 are bolted together and reinforced using pins. Because of this, we do not recommend attempting to disassemble the GN2 in order to use the stages separately.

Hello, My name is Danilo Lind and I am devopment Enginner at ZF Friedrichshafen Ag. (Germany). I am trying to use a combination of the CR1_M and the GN05_M to develop a positionioning device for a test. I would like to remove the base Plate from the GN05_M and screw it directly in a adapter plate (as the two devices dont match) using the 4 screws provided to fix the Base plate. The problem is that I cant find the Information about the Thread of this screws. Could you please tell ?
YLohia  (posted 2018-08-07 09:06:15.0)
Hello Danilo, #2-56 x 3/16 socket head cap screws are used to secure the GN05/M mounting plate to the base plate, but please bear in mind we do not recommend removing the base plate from mounting plate. Doing so may compromise the precise adjustment achieved with the stage, which will then require recalibration or readjusting.

Hi, a bead and the lock screw went off when I tried to mount the GN1 to a post. Now the goniometer only rotates one way but the other direction we have to manually "push" it to rotate. Is there anyway we can fix it? (the bead was missing unfortunately...) thanks!

j.fischer  (posted 2015-12-30 12:04:43.757)
Hi, I would like to use a GN05/M or GN2/M upside down, meaning that I would like to attach my load where the base-plate is right now and I would mount the GN2/M where now the load is supposed to be (likely using a custom baseplate). Is the baseplate removable? Can it be attached to the top surface, or is there another easy way to mount the top surface to another large surface (with custom bores and threads)?
besembeson  (posted 2016-01-04 02:11:11.0)
Response from Bweh at Thorlabs USA: Thanks for contacting Thorlabs. You can use this in the upside down configuration, with reduced load capacity. The base plate is connected to the mounting plate through four cap screws so it can be removed. The mounting plate only has threaded holes (around the central mounting area) so attaching this to the top plate (that also has threaded holes) is not recommended. I will contact you if a special adapter plate is needed.

I'm considering this goniometer for a vacuum application but am concerned about the lubrication of the dovetails. The device appears to be anodized aluminum, if this is the case, would lubrication be necessary? If they are not aluminum, out of curiosity, what are they made of?
cdaly  (posted 2014-08-07 10:25:09.0)
Response from Chris at Thorlabs: Thank you for your inquiry. The main body of the goniometer is made form anodized aluminum. The stage uses apiezon grease, which is vacuum compatible, but the micrometer does not. We may be able to provide one as a custom vacuum version without the micrometer, but due to the tight tolerances on these parts, we would not be able to strip the anodization and would need to make them from scratch.
alrun.thuemen  (posted 2014-05-07 12:05:12.29)
We use this Gonoimeter 6 times in our jig. And in some positions the restoring force is not strong enough. Is it possible to change the spring? If yes, do you have alternatives? Do you have think about caps in different colors for the srews. I think it could be very helpful for making instructions how to use jigs. Thx, Thümen
cdaly  (posted 2014-05-08 04:27:33.0)
Response from Chris at Thorlabs: Thank you for your inquiry. There may be a possibility of replacing the spring in a custom version to increase the restoring force, but we would likely not be able to provide this at lower quantities. I will contact you directly to discuss this further with you. We would not be able to provide customer color coded actuator screws for the goniometers however.

Could you please suggest a method of affixing one of these goniometers to th RP01/M rotation stage?
cdaly  (posted 2013-05-21 13:19:00.0)
Response from Chris at Thorlabs: Thank you for using our web feedback. There's really no direct way to mount the two together. You could use a plate such as C1520/M which will attach to the top of the stage with an M6 threaded stud to give you a good mounting surface for the goniometer, but this is probably going to block the reference marking. Would it be possible to use the PR01/M instead? This has a large enough surface with appropriate mounting holes that the goniometer can be mounted directly to. We also have the TTR001 stage available with tip/tilt/rotation adjustment, though it would not have the full 360 degree range of the RP01.
tcohen  (posted 2012-09-13 13:14:00.0)
Response from Tim at Thorlabs: The main scale has 1 degree graduations and the Vernier scale increments in 10 arcmin graduations as you noted. If the central line on the Vernier is aligned with a degree mark on the moving platform, this is read in degrees. The line on the Vernier scale that is aligned with one on the rotation dial is the value read in 10 arcmins to give a finer scale to read between the main degree graduations. I will contact you to discuss this and your calculation further.
huub.de.graaf  (posted 2012-09-13 09:53:49.0)
I am also struggling with the use of the goniometers. I assumed 1 line (marker) on the goniometer is equivalent to 10 arcmin. This however would mean that 6 full rotations of the goniometer creates a tilt of 25 deg (25*6*10= 1500 arcmin = 25 deg). Somehow I think this is not correct. Please give the correct scale factor.
jjurado  (posted 2011-08-09 18:36:00.0)
Response from Javier at Thorlabs to tech: Thank you very much for your feedback. We will considering adding documentation with instructions on the use of the Vernier scale engraved on our goniometers to the website or to the final product. In the meantime, I will contact you with this information.
tech  (posted 2011-08-09 16:03:16.0)
Why dont you offer any instructions on how to use your goniometers? Specifically,instructions on how touse the vernier scales to obtain the stated accuracy? Just because I bought one of your stages doesnt mean I know how to use it. I assumed instructions would come with the device, but no. Obviously you guys are much more interested in selling your products than you are in making sure your customers know how to use the products.
bdada  (posted 2011-04-13 15:47:00.0)
Response from Buki at Thorlabs to Harald: The maximum load is limited by the pulling force of the springs inside. Therefore, it should be the same even when it is mounted upside down. If you have further questions, please email TechSupport@thorlabs.com
harald.hovland  (posted 2011-04-13 17:09:56.0)
I am interested in a product to mount a camera vertically and adjust it with reasonably good precision. The GNL20/M might be an option if i can mount the goniometer upside-down and hang the camera under the goniometer. The question is if the goniometer can be mounted this way and support this (negative) load. The camera with lens weights approx. 350 gram, and i could probably manage to produce an extra bracket weighing less than 100 g to be within the 1 lb stated. I assume the weight limit is stated for nominal (not upside-down) operation, though?
Greg  (posted 2011-01-13 08:22:38.0)
A response from Greg at Thorlabs to johannes.trapp: In order to change the adjuster, a bushing is needed with the same dimensions as the stock bushing. Unfortunately, we do not have any other bushings that will fit the GN2/M without a redesign of the product. We will contact you to discuss this further.
johannes.trapp  (posted 2010-12-21 09:00:01.0)
Hallo, is there a possibility to change the screws for the GN2/M in order to achieve a higher precision? If so, which screws are compatible? thanks
Thorlabs  (posted 2010-06-28 13:29:27.0)
Response from Javier at Thorlabs to david.thompson: we offer thread adapters that may work for mounting different optics or other components onto the GNL10. For example, if you are looking to mount a prism, you can use our our PM1 and PM2 clamping arms, which have #6-32 threads. We could also discuss the design of a custom plate, although the use of such a plate would shorten the distance to the point of rotation of the stage. I will contact you directly to discuss your application a bit further.
david.thompson  (posted 2010-06-27 17:33:08.0)
I just bought two of these. I didnt look carefully enough at the mounting holes. My lab is basically standardized on 1/4-20. So most of my mounts will not interface easily with these goniometers. Can you recommend an adapter plate? It would be great if that were listed as a possible accessory on this page.
ghegenbart  (posted 2008-06-26 09:27:59.0)
The GNxx/M series products have M3 mounting holes. Please add information on the pitch to the drawings. Both M3-0.20 and M3-0.25 are common, so it may happen that a user has M3 screws that dont fit and he is wondering why.

Dear Sir, This appears to be some thing that We are looking for. May I request you to send us a little more detailed Brochure, for Prism measurements. a. Please confirm whether it is possible to have a digital readout hooked to the above Angles measurement of Prism . b. Will it be possible to have a computer Interface with the said instrument. Please reply even if the accesories are to be procured from else where since we are looking for a total set up with a digital readout and computer interface. In case This instrument is compatible for the accessories mentioned above then perhaps that is what we are looking for. You may suggest also about the vendors who could supply the digital readouts and computer interface suitable and compatinle to your instrument. We are trying to measure the refractive Angles and not mearly reflective angles whcih may please be noted. We shall be obliged for an early reply. Best regards. BOB
