Illumination source brightness is adjustable over 106 dynamic range

DECEMBER 24, 2009--The VLS-100 variable luminance source is a controllable source of uniform, visible illumination for testing cameras, image intensifiers, and visible-to-NIR night vision devices.

DECEMBER 24, 2009--The VLS-100 variable luminance source is a controllable source of uniform, visible illumination for testing cameras, image intensifiers, and visible-to-NIR night vision devices. It is used with I-SITE software or as a standalone, computer-controlled device. The VLS-100 features a 50-mm-diameter source aperture with <2% luminance nonuniformity. The source brightness is continuously adjustable over a dynamic range of 106 that is computer-controlled to within 3% of its set value. An integrated photometer provides real-time monitoring of exit port luminance, allowing closed-loop control. A range of filters and test targets is available to support a variety of performance measurements.

PRESS RELEASE

Optikos Corporation announces their newly-developed VLS-100 Variable Luminance Source

Wakefield, MA - Optikos Corporation has developed the VLS-100 Variable Luminance Source which is a controllable source of uniform, visible illumination for testing cameras, image intensifiers, and visible to near-infrared night vision devices. It is used with I-SITE software or as a standalone, computer-controlled device.

The Variable Luminance Source features a 50 mm diameter source aperture with <2% luminance non-uniformity. The source brightness is continuously adjustable over a dynamic range of 106 that is computer controlled to within 3% of its set value. A range of filters and test targets is available to support a variety of performance measurements

The VLS-100 Variable Luminance Source features:
-Automated variable attenuator and aperture wheel with high resolution stepper motors.
-Integrated photometer provides real-time monitoring of exit port luminance, allowing closed-loop control.
-Filter drawer allows for multiple 50 x 50mm filters to adjust color temperature and spectral output.
-Digitally controlled, laboratory grade power supply ensures constant lamp output and stable color temperature.
-Dual integrating sphere design ensures exceptional illumination uniformity.
-NIST traceable color temperature.
-Custom targets available for objective or subjective metrology testing, boresight measurements, and contrast measurements.
