many component factors and sources in a room. The
dark plastic used in product faceplates can be formu-
lated to act as a highpass filter, reducing the amount of
visible light and other wavelengths landing on the pho-

dors carry plastic materials that may be cut, bent, or
molded. The key to selecting a plastics vendor is to ask
about the wavelength characteristics of the materials.
The more the vendor knows, the more likely the vendor
will be able to help you in a knowledgeable manner
when working on both the industrial design and wave-
length pass characteristics of your IR window. If the
vendor does not know what you are talking about, you
need to find a knowledgeable source for filter materials.
