Light Sources
-
There are many low cost artificial light sources used for illumination or for industrial applications: tungsten or halogen bulbs, fluorescent lamps, LED lamps etc. Some of these sources have regulated intensity of emitted light. However, there very few calibrated light sources of precisely known parameters. A light source can be considered as calibrated when its user can precisely regulate its photometric/radiometric parameters like luminance (or illuminance), radiance (or irradiance) at defined spectrum of interest. Such light sources are needed in many applications among them, in systems for testing night vision devices, VIS-NIR cameras and SWIR imagers. Inframet offers a series of calibrated light sources that can be divides into three groups:

Goniophotometer
-
A goniophotometer is a system to measure the luminous intensity of the source (or illuminance from the source at a given distance) in many different directions from the source. Compared with the sphere method, the goniophotometer method is theoretically free from errors due to differences in intensity distribution of the light source under test. It is applicable to acquire the luminous intensity distribution, luminous flux, spatial color distribution, and luminance distribution of lamps and luminaires.
