開口
レンズの開口(絞り)部はレンズが集光する光の量を制御します。レンズが集光する光量が多ければ多いほど、画像は明るくなります。このことにより、開口サイズは露光時間、つまりカメラのシャッタ速度に影響します。当社でご提供する各レンズの最大開口サイズは、下の表に、f/#(例:f/1.4)の記号で表されるF値で記載しております。F値が増加すると、開口は小さくなり、レンズが集光する光の量も少なくなります。
F値は数式で以下のように定義します。
f/#はF値、fは焦点距離、dは入射瞳径(入射光束の直径)です。
多量の光を集光できるカメラレンズ(つまりF値が小さいレンズ)は、露光時間が短く済むことからファストレンズとして知られています。低光量の状況での使用に適しています。例えば、焦点距離が50 mm、開口F値1.4のレンズは、焦点距離が同じで開口F値が2.5のレンズよりも開口が大きくなるので(シャッタ速度が)速くなります。大きい開口を利用して集光する光量を多くすると、画像の軸上で焦点が合う領域が狭く、つまり被写界深度が浅くなります。異なった開口サイズによる効果を視覚的に説明した画像が、下の表でご覧いただけます。画像は、同じレンズ(MVL12M43、カメラは1/2インチフォーマットDCU224C)を使用し、F値を増加させながら撮影しました。一定の露光時間で撮影したので、レンズが集光する光の量は、F値の増加(約1.4の)毎に1/2ずつ減っています。
焦点距離
焦点距離(FL)は、大まかに定義すると主平面から焦点面までの距離です。カメラレンズにおいては、焦点距離がカメラシステムの視野範囲を決定します。焦点距離が長いと、視野範囲が狭くなります。一般的なガイドラインとして、焦点距離が50 mmのレンズと35 mmフォーマットカメラの組合せは、人間の目と大体同じ視野範囲を作り出します(対角線で約53°)。下の表では、人間と同じ視野範囲を得るために必要な焦点距離を、異なるセンサーフォーマット毎に記載しています。
画像の視野範囲に関連して、レンズは一般的に3種類に分類されます。レンズの焦点距離がセンサーフォーマットの対角線長に近く、人間の視野範囲に近い画像を生成するレンズは、そのセンサーフォーマットに対して標準レンズであるとみなされます。広角レンズの焦点距離は標準レンズより短く、広い視野範囲の画像を生成しますが、画像の端に樽型歪が現れる傾向があります。最後に、標準レンズより焦点距離が長いレンズは望遠レンズとして知られています。視野範囲が狭くなりますが、画像内の被写体が拡大されます。
1/2インチフォーマットCCDカメラDCU224C
右は、上記を説明するために同じカメラで3種類のレンズを用いて撮影した画像です。レンズの焦点距離が長くなると、写真の被写体の倍率は大きくなり、視野範囲が狭くなります。画像の物体は、約254 mmの間隔で、次のような順番で並んでいます: Polaris™固定式モノリシックミラーマウント(カメラから254 mm)、Ø12 mmおよびØ1/2インチポストとミラーマウントKM100(カメラから508 mm)、ポスト付き回転マウントRSP1(/M)(カメラから762 mm)。1番左の画像の撮影に使用したMVL4WAは広角レンズですが、画像の左端のドア枠がゆがんでいるのがはっきりとご覧いただけます。

様々なカメラセンサとレンズフォーマットの組合せ
CCDやCMOSセンサ付きの現代のカメラは、カメラセンサーフォーマットが指定されています。同様にレンズも特定のカメラフォーマットに対して適切なイメージングが実現できるよう設計されています。このフォーマット指定(例：1/2インチ、2/3インチ、4/3インチ)は、ブラウン管でビデオを録画していた頃からの名残で、ある画像サイズを得るために必要なブラウン管の外径のことです。右の図では標準的なカメラフォーマットサイズを数種類比較しています。イメージングシステムにおいてカメラとレンズが同じフォーマットで設計されていることが理想的です。しかし、異なったフォーマットのカメラとレンズを組み合わせることも可能です。異なった組み合わせは、結果的にビネット(口径食)またはクロップ(切抜いたような効果)が画像に現れます。
ビネット
ビネット(Vignette、口径食)はレンズフォーマットがカメラフォーマットより小さいときに発生します。ビネットが発生すると、センサの領域が不完全に露光されるため、暗い輪が画像の縁周りに現れます。ビネット効果は、下の2枚の画像でご覧いただけます。どちらも同じ4/3インチフォーマットカメラを使用しています。左の画像は、焦点距離12 mmの4/3インチフォーマットレンズを使用しています。画像をフルに生成していますが、縁周りが若干暗くなっています。ビネット効果があまり現れなかったのは、レンズのエッジ部分の透過率が低い設計になっているためです。もう1つの画像では、2/3インチフォーマットレンズを同じ焦点距離で使用しました。写真の縁周りの暗い輪がはっきりと現れています。この例のように効果がはっきり見えてしまうため、イメージングの際にはカメラセンサより小さいフォーマットのレンズのご使用はお勧めしておりません。

クロップ
レンズフォーマットがカメラフォーマットより大きい場合、画像にはクロップ(crop、切抜き)と呼ばれる効果が現れます。この時、画像はフルに生成されていますが、サイズが小さくなって(つまり、切抜かれて)います。これはセンサがイメージの一部のみを捉えているからです。クロップファクタ(切抜取込数値)または焦点距離換算倍率は、クロップ(切抜き)量を数値化するもので、レンズの設計フォーマットの対角線長をセンサーフォーマットの対角線長で割った割合と定義されます。右の表では、1/3インチ、1/2.9インチ、1/2インチ、1/1.8インチ、2/3インチ、1インチならびに4/3インチフォーマットレンズ・センサすべての組合せのクロップファクタ(切抜取込数値)がご覧いただけます。
クロップにより切り抜かれた画像は、焦点距離がより長いレンズ(つまり、より狭い視野範囲)で撮影したように見えますが、像を拡大しているわけではありません。クロップ(切抜き)効果は、Adjusted Focal Length(換算焦点距離)で数値化することができます(クロップファクタにレンズの焦点距離を乗じた数値と定義します)。例えば、焦点距離が50 mmの1インチフォーマットレンズを使用して1/2インチフォーマットセンサーカメラで撮影した場合、Adjusted Focal Length(換算焦点距離)が100 mmの画像を生成します。視野範囲は100 mmレンズを使用したように狭くなりますが、画像に映る物体のサイズは同じです。右の表では、こちらでご紹介するすべてのレンズのAdjusted Focal Length(換算焦点距離)について、異なるセンサーフォーマット毎に掲載しています。
下は同じレンズを使用した1/2インチフォーマットならびに1/3インチフォーマットカメラで撮影した画像で、この効果を視覚的に説明しています。1/3インチフォーマットカメラが生成した画像は、1/2インチフォーマットを使用して生成した画像よりも切抜かれている(クロップ効果が現れている)ことが分かります。しかし、両画像の物体のサイズの倍率は同じです。

(posted 2024-10-13 16:11:53.243) Hello - I'm curious to understand what the difference is between the MVL50M23 and the MVL50TM23. The latter is "10MP Compatible" and is also (therefore) much more expensive.
Granted, I could fathom that the "10MP" label means the camera can support higher resolution imaging. But how much worse is the resolution for the regular variant? Is there perhaps a section in the Tutorials that explains this? jdelia
(posted 2024-10-14 03:55:18.0) Thank you for contacting Thorlabs. For these two parts, we specify the following: Center 100 lp/mm, Corner 80 lp/mm for MVL50M23 and Center 200 lp/mm, Corner 160 lp/mm MVL50TM23. While we do not offer an explicit tutorial on these lenses, we have reached out to you directly via email to discuss your application. ILIYA SHOFMAN

(posted 2024-08-15 12:36:39.997) There seems to be a discrepancy in dimensions between the step model and the CAD drawing available for download for this product. The length between the flange and the end of the C-mount thread in the CAD drawing is shown to be 4.1 mm, while in the step model I measured it to be 6.52 mm. Natan Osterman
(posted 2024-06-11 10:35:13.703) Hi,
a measurement given in the documentation of MVL50M23 is wrong!
The diameter of the back part of the objective (close to the thread) is not 33.0 mm but rather 34.0 mm! This error has just costed me 500€ as many objective holders have already been manufactured and anodized but now the lens does not fit in.
Best regards,

(posted 2024-08-14 12:07:18.0) Thank you for reaching out to us with this inquiry. Apparently this was a mis-documentation by our vendor on their website, which propagated to our own website. At the time of posting, we are working with our vendor to get updated models and drawings. I have contacted you directly to discuss how we can compensate you. Peter Rogin
(posted 2024-03-04 08:47:35.083) The mechanical dimensions of the recently purchased lens differ from the technical drawings available online. As a result, a customized mount had to be redesigned. Not a big deal, but having the drawings up to date would certainly be helpful. jdelia
(posted 2024-04-04 12:52:23.0) Thank you for contacting Thorlabs. I reached out to you to clarify the discrepancies, and after discussing it with our vendor, Navitar, I confirmed that our drawing was indeed out-of-date. We are currently looking into updating the drawing for the MVL100M23 on our website. Shahad Al-Gburi

(posted 2018-10-15 11:45:14.0) Thank you for contacting Thorlabs. The MVL35M23 is directly compatible with the DCC1645C. However, the MVL35M23 is not 30 mm cage compatible. You can consider using its M27 x 0.5 filter threading with our SM1A36 adapter to make it SM1 compatible, which can then be incorporated into our cage systems more easily. sanket.shah

(posted 2016-05-13 15:25:55.197) Hello. We're using the MVL12M1 lens attached to an iDS camera (http://www.1stvision.com/cameras/IDS/dataman/UI-3370CP-C-HQ.pdf). The lens/iDS combo is looking into the eyepiece of another camera, we'll call it camera B, to take pictures of what a human eye would see looking into camera B. In order to accurately simulate the human eye, the entrance pupil of the MVL12M1 must be located ~25mm from the vertex of the eyepiece element. The issue we're having is how far to place the lens behind camera B's eyepiece, that is, where is the entrance pupil located within the MVL12M1 lens? Thank you. besembeson

(posted 2015-02-05 15:08:16.797) Is it possible to use the MVL7000 zoom lens with any of the magnifying lens or extension tubes available under the "High-Magnification Zoom Lens Systems for Machine Vision" section so as to effectively have a teleconverter to multiply the zoom range? If not, can you recommend any teleconverters compatible with MVL7000 ? jlow
(posted 2015-02-10 11:59:37.0) Response from Jeremy at Thorlabs: The extension tubes and magnifying lens used in the high-magnification zoom lens systems are not compatible with MVL7000. We do not currently sell any teleconverters compatible with the MVL7000. I will contact you directly to discuss more about this. paul.hockett
(posted 2015-01-28 10:12:56.937) Hi,
Is it possible to get transmission curves for the MVL16M1, or the Navitar lens range in general (assuming they're all pretty similar)?
Also, related to this: do any of the machine vision lenses transmit reasonably well down to around 350nm? For our application we'd ideally like to transmit light ~350 to 500nm, but can probably tolerate a cut-off of ~400nm (as seems typical VIS-optimized lenses) if we have to.
Thanks,
Paul jlow
(posted 2015-01-29 03:27:24.0) Response from Jeremy at Thorlabs: We are working on putting the transmission curve for the C-mount lenses on the website. Typically these lenses do have poor transmission below 400nm. I will contact you directly to provide the curve for this. fmu

The cameras we offer are based off of silicon technology and would detect light from 400-1100nm(Monochrome only), but the color camera versions have IR filters that filter out the IR light so they would only detect light from 400-700nm. I will email you directly to find out which camera you are referencing so we can provide more accurate data. soia_1_is
