Comparison of Standard Sensor Sizes (dimensions in mm)
The following figure graphically shows the use of two different lenses with the Genie HM 1400 which has a sensor
of 10.40mm by 7.60mm (a diagonal of 12.88mm).

The outer circle shows the illumination coverage of a 1 inch lens where a sensor of up to 16mm diagonal is
evenly exposed.

The inner circle shows the illumination coverage of a 2/3 inch lens where a sensor of up to 11mm diagonal is
evenly exposed.
The obvious conclusion is that a 2/3 inch lens will produce image vignetting at the sensor edges, while a 1 inch lens
will evenly expose the sensor but at a greater cost in optics. The choice in lens is therefore a trade off of cost verses
application requirements.
