Luminance Colorimeter
XYL-VI
The XYL-VI Luminance Photoelectric Colorimeter changes the traditional structure thoroughly, employs the digital X(λ), Y(λ), Z(λ) sensors to replace the traditional analogue sensors, employs the digital signal measurement system to replace the traditional analogue measurement system. The instrument has no analogue unit, thus it is very simple to overcome the zero drift that is impossible to be avoided in traditional colorimeter. The digital sensor has a large dynamic range. Moreover, it possesses strong anti-interference ability and it has high accuracy. The XYL-VI Luminance Colorimeter contains internal RS232 computer interface. The calibration is done by software. It is suitable for monitoring and remote applications. The XYL-VI Luminance Colorimeter can be calibrated by XYL-VI Luminance Colorimeter software to sample the data and print out the results. It can also be corrected by other standard light sources to obtain very high measuring accuracy of x, y color coordinates and color temperature. It is a real-time measuring system and run under Windows2000/XP.

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:
