Off-Axis Performance

The light entering a polarizer is typically a cone. The size

of the cone depends upon the f/number of the system.

Most systems us a cone half angle of less than 20º.

with angle of incidence, resulting in uniform system

performance over the aperture. This is illustrated in the

typical off-axis 1/2 angle performance graphs of

transmittance and contrast shown below.
