Light Source facilitates imaging device PRNU comparison.
Press Release Summary:
December 12, 2012 - Built around 8 cm dia sphere with 19 mm dia light output port, ISS-8P-HP Integrating Sphere Light Source features uniformity equal to or better than 98% within 90% of output, and is useful as calibration standard for Photo-Response Non-Uniformity comparison. Unit offers selectable 10–100 W QH lamps and 3 manually interchangeable neutral density filters with OD0, OD1, and OD2 optical densities corresponding to 100%, 10%, and 1% light throughput for fast H-M-L High Medium Low adjustment of output.

H-M-L Intensity Controllable Uniform Light Source for Imaging Device PRNU Comparison
Press release date: December 4, 2012
Gigahertz-Optik’s new model integrating sphere source ISS-8P-HP features uniformity equal to or better than 98% within 90% of its output port featuring a fast H-M-L High Medium Low setting of intensity level using interchangeable attenuators. This quick three setting adjustment of light level is highly desirable in production comparison applications.
The ISS-8P-HP is built around an 8cm diameter integrating sphere made from Gigahertz-Optik’s highly diffuse reflective and stable synthetic ODM98 coating with a 19mm diameter light output port.
Its light source design offers selectable 10 to 100 W QH lamps and features three manually interchangeable neutral density filters with OD0, OD1 and OD2 optical densities corresponding to 100%, 10% and 1% light throughput for fast H-M-L adjustment of light output. This method is faster than using a variable aperture plus the hole pattern design attenuator minimalizes color temperature drift. A fan is supplied to air cool the lamp socket to ensure lamp life and system stability.
Optional accessory components like a Gigahertz-Optik LPS series high resolution lamp power supply, optometer with an illuminance, luminance or illuminance & color monitor detector complete the system.
