The uniform light source ISS-8P-HP is based on a ODM98 coating and offers an 19 mm light entrance port. Furthermore the system is equipped with a LS-OK30 light source and a filter holder which (LS-OK30-HPA) can be loaded by an OD1 and OD2 filter.
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.
