The Camera Lenses sold here are specifically designed to be used with 1/2", 2/3", 1", or 4/3" sensor format cameras and are well-suited for machine vision applications. Thorlabs offers lenses with fixed focal length (i.e., prime lenses) that offer superior optical performance at focal lengths from 3.5 mm to 100 mm, as well as a 2/3" format zoom lens with an adjustable focal length of 18 mm to 111 mm. All lens models are equipped with lockable focus and aperture rings.
Some lenses are designed for improved aperture or resolution performance. Because of the simplified optical design, some prime lenses are designed as fast lenses with large maximum apertures up to f/0.95 (see the Camera Lens Tutorial tab for details). Thorlabs also offers 2/3" format lenses at 5 mm, 25 mm, and 50 mm fixed focal lengths that feature 200 lp/mm resolution, commonly referred to as 10 megapixel (10 MP) lenses. These lenses are the ideal choice for high-end inspection or high-resolution imaging applications. For more information on these lenses, Modulation Transfer Function (MTF) plots can be found in the 10 MP Lens Data tab above.
Selecting an appropriate camera and lens pair can significantly improve image quality. A lens should generally not be used with camera sensors that have a larger format than the lens. While these lenses can be used with a smaller format camera, the resultant image will be cropped (see Camera Lens Tutorial tab for details). See the table below for a list of sensor formats for Thorlabs cameras.
Lenses that are equipped with C-Mount (1.00"-32) threads are fully compatible with most of our C-Mount CMOS Cameras and our line of Scientific-Grade Cameras. CS-Mount cameras are compatible with these lenses when using a CML05 CS- to C-Mount adapter.

Aperture
The aperture of the lens controls the amount of light that a lens can collect; the more light a lens collects, the brighter the image. Because of this, the aperture size affects the exposure time and therefore the speed of the camera. Thorlabs provides the maximum aperture size in the tables below for each lens in terms of the f-number, which is expressed using the symbol f/# (e.g., f/1.4). As the f-number increases, the aperture opening becomes smaller and less light is collected by the lens.
Specifically, f-number is defined as:
where f/# is the f-number, f is the focal length and d is the entrance pupil diameter.
Camera lenses that can collect a lot of light (i.e., a low f-number) are known as fast lenses as they can be used with shorter exposure times and are ideal for low-light conditions. For example, a 50 mm focal length lens with a f/1.4 aperture has a bigger aperture and is therefore faster than a lens at the same focal length with a f/2.5 aperture. While using larger apertures increases light collection, doing so reduces the axial in-focus region of the image, known as the depth of field. To illustrate the effect of different aperture sizes visually, the table below shows a sequence of images taken with the same lens (MVL12M43 on a DCU224C 1/2" format camera) for increasing f-numbers. Because the images were taken at constant exposure, for each f/# increase (by a factor of ~1.4) the amount of light collected by the lens is reduced by half.

Focal Length
The focal length (FL) is roughly defined as the distance from principal plane to the focal plane. For a camera lens, the focal length determines the field of view of the camera system; the longer the focal length, the smaller the field of view. As a general guideline, a 50 mm focal length lens and 35 mm format camera combination produces roughly the same field of view as the human eye (~53° diagonal). The table below lists the focal lengths needed to achieve the same field of view as the human eye for different sensor formats.
There are three general classifications for lenses related to the image field of view. A lens with a focal length close to the diagonal length of the sensor format produces an image with a near-human field of view and is considered a "normal" lens for that sensor format. A wide-angle lens has a focal length shorter than normal, which produces a wider field of view but has a tendency to exhibit barrel distortion effects towards the edge of the image. Finally, a lens with a focal length longer than normal is known as a telephoto lens, which has a smaller field of view and a greater magnification of objects in the image.
DCU224C 1/2" Format CCD Camera
To illustrate this, the sequence of three images to the right were taken with the same camera with three different lenses. As focal length of the lens increases, magnification of the objects in the photos increases while the field of view decreases. The items in the image are each roughly spaced in 10" (254 mm) increments in the following order: Polaris™ Fixed Monolithic Mirror Mount (10" from camera), Ø1/2" post with KM100 mirror mount (20" from camera), and post-mounted RSP1 rotation mount (30" from camera). The MVL4WA used to shoot the first image is a wide angle lens which clearly distorts the door frame on the left edge of the image.

Combining Different Camera Sensor and Lens Formats
Modern cameras that use CCD or CMOS sensors are specified for a camera sensor format, and similarly, lenses are designed to provide optimal imaging for a specific camera format. This format designation (e.g., 1/2", 2/3", 4/3") is a hold-over convention from when video was recorded using cathode-ray tubes and refers to the outer diameter of the video tube required for a given image size. The diagram to the right illustrates the size difference between several standard camera formats. In the ideal imaging system, a camera and lens would be designed for the same format, however, it is also possible to use camera/lens combinations with different formats. Doing this will have an effect, either vignetting or cropping, on the resulting image.
Vignetting
Vignetting occurs when the lens format is smaller than the camera format. When this occurs, the area of the sensor is incompletely exposed, causing a dark ring to appear around the borders of the image. The vignetting effect is illustrated in the two images below, which were both captured using the same 4/3" format camera. In the image to the left, using a 12 mm focal length, 4/3" format lens produces a full image with slight dimming around the edges. This minor example of vignetting is due to the lens design which has decreased transmission at the edge of the lens. On the other hand, a 2/3" format lens at the same focal length produces a prominent dark ring around the photo edge. As the latter example is very visually apparent, we do not recommend using lenses with smaller formats than the camera sensor for imaging.

Cropping
When the lens format is larger than the camera format, the effect on the resultant image is known as cropping. In this case, a full image is produced but at a smaller size (i.e. cropped) because the sensor is only capturing a fraction of the complete image. A crop factor or focal length multiplier quantifies the amount of cropping and is defined as the ratio of the diagonal length of the lens' design format divided by the diagonal length of the sensor format. The crop factor for all possible 1/3", 1/2.9", 1/2", 1/1.8", 2/3", 1", and 4/3" format lens/sensor combinations are shown in the table to the right.
An image that is cropped appears as if it was taken with a lens of higher focal length (i.e. a smaller field of view), but does not magnify the image. The cropping effect can be quantified using an adjusted focal length (defined as the crop factor multiplied by the lens focal length). For example, an image taken using a 1" format, 50 mm focal length lens with a 1/2" format sensor will produce an image with an adjusted focal length of 100 mm. While the field of view is reduced as if using a 100 mm lens, objects in the image will remain at the same size. The table to the right lists all of the lenses offered on this page with the adjusted focal length for different sensor formats.
The images below illustrate this effect visually using two images taken using the same lens with 1/2" and 1/3" format cameras. The image taken using the smaller 1/3" format camera produces an image that is cropped compared to the image taken using the 1/2" format camera. Note, however, that the objects in both images remain at the same magnification.

(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 2024-08-15 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.

(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 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

Where can I ZEMAX file about MVL35M1?
If you offer the ZEMAX file of MVL35M1, I would like to get from you. I can't find ZEMAX file on your website now.
Please confirm my message and I will wait your reply.
Sincerely,

(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
