Window Material and Color
CIS
’s responsiveness (mainly to wavelengths of white light
)
should be taken into consideration when
choosing window material and color, in order to achieve the possible highest spectral transmission, lowest
haze level and homogeneous refractive index. It is suggested to use PMMA or optical glass with spectral
transmittance over 90% and haze less than 1%. Whether to use an anti-reflection coating or not depends
on the material and application needs.
Scratch Resistance and Coating
Scratch on the window can greatly reduce engine performance. It is suggested to use abrasion resistant
window material or coating.
Window Size
The window must not block the field of view and should be sized to accommodate the illumination
envelope shown below.
