In case of the longer wavelength, lower straying at the surface and thus a better screening of the test object is to be expected, however the sensitivity of common CCD camera sensors is increasingly reduced.
Therefore preferably LEDs with a range of approx. IR illumination The wavelength range from approximately nm to 1 mm, i.

For longer-wave IR ranges, Peltier-cooled sensors and special semiconductor materials must be used. In industrial machine vision, however, most of the applications are located in the near infrared range, which comprises the spectral range from to nm.
IR bgii is often also called thermal radiation. Longer-wave radiation is electromagnetic radiation and therefore oscillates less frequently than shorter-wave radiation and thus generates less interaction with the material.
When using IR radiation it is sometimes even possible to look through an object. It is therefore capable of penetrating deeper into the material and generates fewer surface reflections than short-wave light.
Bg IR radiation is not visible to the human eye, it can be applied particularly well at workstations where normal light would be disturbing. Cameras for the evaluation of the medium IR range are called thermographic cameras or thermal imaging cameras.
All visible colors except black, very dark colors with black admixtures and metallic colors disappear. All visible colors disappear on banknote and credit card except for black and special security features.

In the range between bbi and nm normal monochrome CCD cameras can still be used for inspection, the sensitivity of which indeed increasingly diminishes but is basically sufficient.
The optics no longer consists of normal glass, but are made of materials like germanium.
