15 NEDXCM4040SAT2 UME-0009-022.3 Optical InterfaceFor XCM4040SAT2 the Nikon F-mount is available.The amount and wavelengths of light required to capture useful imagesdepend on the intended use. Factors include the property, speed, the objectsspectral characteristics, exposure time, the light source characteristics, thespecifications of the acquisition system and so on.The exposure amount (exposure time x light amount) is the most importantfactor in getting desirable images. Please determine the exposure amountafter studying what is most important to your system.Keep these guidelines in mind when setting up your light source:z LED light sources are relatively inexpensive, provide a uniform field andlonger life span compared to other light sources. However, they alsorequire a camera with excellent sensitivity.z Halogen light sources generally provide very little blue light but havehigh infrared light (IR) proportions.z Fiber-optic light distribution systems generally transmit very little bluelight relative to IR.z Metal halide light sources are very bright but have a shorter life spancompared to other light sources.Generally speaking, the brighter the light sources, the shorter the life span.CMOS image sensors are sensitive to infrared (IR). We recommend usingdaylight color fluorescent lamps that have low IR emissions. If you use ahalogen light source, to prevent infrared from distorting the images use an IRcutoff filter that does not transmit wavelengths.
