Gigahertz-Optik Intros Uniform Light Source
Uniform light source for imaging device testing.
Newburyport, MA — Gigahertz-Optik has introduced a new model integrating sphere light source, ISS-8P-HP, which reportedly provides uniformity equal to or better than 98 percent within 90 percent of its output port. The new source also provides a 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 integrating sphere light source provides for uniform and variable light output, necessary for calibration light source standards used for PRNU (Photo-Response Non-Uniformity) comparison of imaging systems and sensors.

The ISS-8P-HP is built around an 8cm diameter integrating sphere made from the company's highly diffuse reflective and stable synthetic ODM98 coating with a 19mm diameter light output port. Its light source design offers selectable 10 to 100W QH lamps and three manually interchangeable neutral density filters with optical densities corresponding to 100 percent, 10 percent and 1 percent light throughput for fast H-M-L adjustment of light output. According to the company, this configuration results in faster adjustments compared to using variable aperture devices; plus, the ISS-8P-HP hole pattern design attenuator minimizes color temperature drift.

A fan is supplied to air-cool the lamp socket to ensure lamp life and system stability. Optional accessory components include the company's LPS series high resolution lamp power supply, optometer with an illuminance, luminance or illuminance and color monitor detector.
