Light source for radiometer / spectroradiometer testing

Gamma Scientific announces the versatile, new RS-5NVIS Digital Light Source to test and calibrate ANVIS radiometers and spectroradiometers. The advanced instrument offers high resolution and digital brightness control that provides near-perfect linearity and uniformity and is designed to maintain the lowest uncertainty measurements possible. The calibration light source is ideal for compliance testing in applications such as cockpit display backlights where lighting changes from tungsten and fluorescent to solid-state LEDs.

The compact RS-5NVIS is based on the highly reliable RS-5 Digital Light Source system which features a feedback-stabilized LED optical head with a diffusely illuminated area that can be filtered. The device features a light level setting to 1 part in 65,535 in absolute, NIST-traceable, ANVIS radiance and luminance units. The linearity deviation is less than 0.25% RMS of full scale over the entire brightness adjustment range. This extremely accurate light measurement instrument delivers an astonishing 100 times longer light source lifetime than previously available. The lamp rarely, if ever, needs changing, resulting in nearly zero downtime for the user.

Flexible, intuitive and easy to integrate, the RS-5NVIS is equipped with both a manual control and a simple ASCII computer interface control via the built-in RS-232 port.
