Monochromatic light

The color of light is one of the five factors affecting lighting. Depending on its color, we are able to group the light in monochromatic light, white light or RGB light. Each of these three groups will contribute with different characteristics that we will have to take advantage of for inspecting the objects.

In DCM Sistemes, the references and their colors for monochromatic light are the following:

Colour	Wavelength	Code	Availability	Light type
UV-	365nm	365	Standard	Monochromatic
UV	400nm	400	Standard	Monochromatic
Royal Blue	455nm	455	Custom *	Monochromatic
Blue	470nm	470	Standard	Monochromatic
Green	525nm	525	Standard	Monochromatic
Red	630nm	630	Standard	Monochromatic
Cherry Red	730nm	730	Custom *	Monochromatic
IR	850nm	850	Standard	Monochromatic
IR+	940nm	940	Custom *	Monochromatic
White	-	W00	Standard	White
RGB	-	RGB	Standard	RGB

* Wavelengths 455nm (indigo), 730nm (cherry) and 940 (infrared+) are available on demand for the ALB, AMS, AUB, DOL, DOM (only DOM5652B, DOM5652C, DOMB2B1A), PLA, PLC, PRA, PRC, PRF, PRH, PRK and PRL series.

The monochromatic light is the one formed by components of a single color. That is, the light that has a single wavelength corresponding to each color. It is normally used in monochrome cameras. Very useful to highlight some specific features, since each color provides better visibility in certain aspects and by contrast, since all opposite colors are absorbed. On this type of light, you can add filters to separate bandwidths or to reduce effects of ambient light.

The ultraviolet light and infrared light, although outside the visible spectrum, they are both very useful to inspect materials such as polymers, where the infrared light is considerably more effective.
Also useful when the contrast of color difference is not very apparent, since this light is based on differences in composition planes.

Ultraviolet light is used on surfaces that react to this light by returning a longer wavelength light than it is UV, which is called fluorescence and that is what the camera captures.
