Camera System

Telecentric Lens

The camera assembly integrated into the Horizon is a compact assembly of
optics, lighting and a standard CCIR camera. The camera is fitted with a split
optic unit to allow the camera to capture the image from the stencil and board at
the same time. Thereby, eliminating the relative movement between the images
captured. The camera assembly incorporates 'Telecentric Lenses' and 'Flat
Lighting'.
The optic unit within the camera assembly uses telecentricity to ensure that
board warping, distance between camera and board and the actual position of the
fiducials within the field of view do not affect the alignment accuracy.
