Window Material And Color; Scratch Resistance And Coating; Window Size - Newland EM2039 Series Integration Manual

Window Material and Color

Wavelengths of illumination and aiming beams should be taken into consideration when choosing window
material and color, 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 the performance of the EM2039. 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 aiming and
illumination envelopes shown below.
