Super-Eye™ Telecentric Lenses
The table below shows the 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, or spacer increments of 0.25mm. The WD tolerance is not a reflection of the depth of field. If you need different WDs, contact Light Works.
Distortion: For distortion data when other camera formats are used, contact Light Works.
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.
* 3Field limited by 46mm diameter maximum clear aperture of lens. Some vignetting may occur at the edge of the field as well.
