TCLWD040-110-3M

Description

Object field of view (mm x mm). For the fields with the indication “Ø =”, the image of a circular object of such diameter is fully inscribed into the detector.
Working distance: distance between the front end of the mechanics and the object. Set this distance within ±3% of the nominal value for maximum resolution and minimum distortion.
Working f-number (wf/N): the real f-number of a lens in operating conditions.
Maximum angle between chief rays and optical axis on the object side. Maximum (guaranteed) values are listed.
Percent deviation of the real image compared to an ideal, undistorted image.
At the borders of the field depth the image can be still used for measurement but, to get a very sharp image, only half of the nominal field depth should be considered. Pixel size used for calculation is 3.45 μm.
Object side, calculated with the Rayleigh criterion with λ= 520 nm
Measured from the front end of the mechanics to the camera flange.
