With the help of the filters OD1 and OD2 and an empty filter (OD0) the radiance/luminance of the sphere can be adjusted in three steps. A quality measure for the intensity adjustment is a constant color temperature and no change in the homogeneity of the light entrance port. Both is achieved by the ISS-8P. A typical application for this set-up is pixel-uniformity calibration of imaging systems at three different luminance or radiance levels. The filter exchange is faster than intensity adjustment using a variable aperture.
The light source can be equipped with LF-F or LH-F-UV quartz halogen lamps in the range of 5 W to 100 W. The power will be selected according to the needed radiance/luminance.
A calibration with included calibration certificate (cd/m²) and/or spectral radiance (W/(m²sr)) which is traceable to a national standard can be optionally purchased. The calibration is done by our internal calibration laboratory.
For operation an optional quality current regulated power supply of the LPS series can be used.
