Makro Varon™ 4.5/85 CAS 0.5x-2.0x
A 62 mm image circle, low distortion and
excellent chromatic correction make the MacroVaron™ lens
ideal for high-resolution line scan applications up to 12 (and down
to 5 micron-pixel sizes), such as those used in flat panel
display (FPD) and printed circuit board
(PCB) inspection systems.
The relative illumination of the lens is
virtually constant over the entire image height, enabling the use of
the full size of the sensor. This uniformity of light eliminates the
need for electronic compensation, thus minimizing the noise of the
camera signal. The 85 mm focal length of the MacroVaron™
lens reduces the required working distance, which decreases the
space needed for the camera-lens assembly.

Makro Varon™ 4.5/85 fixed beta
This lens is also available with a fixed
magnification adjustment, see table below, and is called
Makro Varon™ fixed beta. The technical data and the
optical performance are the same as the variable lens version
described above.
