Mini-Super-Eye™ Telecentric Lenses
The table below shows the standard Mini-Super-Eye™ model numbers and specifications. For all of these, the following also applies.
• C-mount (converts to cs-mount with the usual 5mm spacer)
• Fixed focus
• Adjustable/lockable aperture
• Optical performance data is for white light illumination.
• Use of LED or filtered light sources may even improve the performance.

Magnification & Field of View (FOV): These are the nominal specifications. The tolerance in each case is +/-3%. This tolerance is not a reflection of the magnification change over the depth of field. See below.
Working Distance (WD): The maximum shown is the nominal working distance when no extension is added. Adding c-mount extensions and spacers between the lens and the camera will reduce WD without affecting magnification, depth of field, or distortion unless noted. The minimum WD shown is the approximate minimum possible using conventional extensions in increments of 5mm. Unless noted, the tolerance on the nominal WD is +/-2mm. This tolerance is not a reflection of the depth of field. If you need different WDs, contact Light Works.
Distortion: This specification is shown for 1/2” format camera FOVs. The exceptions are the lenses for which only 1/3” format FOVs are shown.
MTF Depth of field: For all lenses (unless noted), the MTFDOF is shown for white light illumination with the lens at F/16, an image plane frequency of 20 lp/mm, and an MTF cut-off of 30%. Furthermore, the MTFDOF is indicated for the noted camera format. For performance data under different conditions, contact Light Works.
Magnification Change: Some vendors use the term “telecentricity” for this property. They state telecentricity using units of angle. A more directly useful specification is a statement of how much the magnification changes when the viewed object changes its distance from the lens. For all these lenses, unless noted, when the object moves over the range of the MTFDOF, the magnification changes by less than 0.01%. Because these are true double telecentric designs, in most cases that specification applies over a much greater range. Contact Light Works for more details.
* Vignetting (edge light loss) occurs at the corners of the FOV.
‡ Vignetting (edge light loss) occurs at the corners of the FOV for longer working distances
NOTE: At this time, Mini-Super-Eye™ lenses are built to order. Most models (even custom units!) can usually be shipped in 1 to 2 weeks ARO.
