TF Series
Lenses for 3-Sensor & MultiSpectral Prism-based Cameras
Standard Industrial C-Mount lenses often are incompatible with prism-based cameras. The mechanical clearance of the back side of the lens can strike the front surface of the prism.
The TF Series limits the backside protrusion of the lens to allow for clearance in front of the prism.
In addition, the TF Series is critically designed to provide high spatial accuracy for each filtered corresponding to each color or specral plane.
3-CCD/CMOS color cameras are equipped with three image sensors; one each for blue, red and green—three of the colors separated by a prism.
