ISS-50-SVA-V01 Integrating Sphere Source

The model ISS-50-SVA-V01 integrating sphere source is designed to meet the needs of the most common uniform light source applications:

• Pixel uniformity and pixel linearity calibration of imaging systems with very large dynamic luminance range
• MTF calibration of imaging sensor resolution where a slit target at a specified distance is uniformly illuminated by the integrating sphere source
• Luminance or spectral radiance sensitivity calibration of imaging devices or luminance meters

The ISS is built with a 50cm diameter barium sulfate ODP97 coated integrating sphere with a 200mm diameter light output port. Intensity is controlled in steps using three internal lLS-IS1.5 light sources and varied with the LS-OK30 light source with LS-OK30-VA variable aperture. The electronics includes the X1-RM optometer for read-out of the photometric reference detector and on/off control of the four LPS-100-RM lamp power supplies supplied. Lamp on/off and variable aperture are manually operated. The color temperature of the light source is set to 2856K.
Calibration of luminance in cd/m², xy uniformity and luminance uniformity is performed by Gigahertz-Optik’s calibration laboratory for optical radiation measurement.
