Telecentric lenses for large linear detectors

TC 4M and TC 2M SERIES:

TELECENTRIC LENSES FOR LARGE LINEAR DETECTORS UP TO 1" and 4 Mpixels

Some of the most commonly used large matrix detectors and some of the most representative industrial cameras using these kinds of sensors are listed below.
Select the lens that best suits your application by choosing the column where the camera (detector) you are using is listed and scroll down the column to find the field of view dimensions that are the closest to your needs.
All the lenses listed below can be equipped with a C or F-mount interface (ordering code: “P/N”+“/F” for F-mount and “P/N”+“/C” for C-mount, e.g. TC 4M 64/F). Custom mounts can be supplied upon request.

TC 2M 192

All the above listed lenses show the following optical specifications:
Distortion < 0.1%
Telecentricity: better than 0.1°
working F-number: 16
CTF @50lp/mm: > 30%

(1)

Working distance: best focus front lens to object distance. Set this distance within +/- 3% of the nominal value to optimize distortion

(2)

Working F-number: the real F-number of a lens when used as a macro. Lenses with smaller apertures can be supplied on request

(3)

Out of this interval the CTF contrast falls below 50% of the nominal value; the field depth can be increased by a smaller diapragm, available on request

(4)

Maximum slope of principal rays inside the lens: turned in millirad. tells which is the maximum measurement error for any millimiter of object displacement

(5)

Measured from the end of the mechanics to the camera flange

(6)

For the fields with the indication "Ø =" the image of a circular object is inscribed inside the short detector side

(7)

The 1/1.8" FOV for TC 12 XX lenses can show some vignetting at the image corners, as the lens is optimized for 1/2" detector
