SAN DIEGO, Sept. 9, 2008 – Gamma Scientific has unveiled the RS-5NVIS digital light source to test and calibrate ANVIS radiometers and spectroradiometers.

Suitable for compliance testing in applications such as cockpit display backlights where lighting changes from tungsten and fluorescent to solid-state LEDs, the light source features a feedback-stabilized LED optical head with a diffusely illuminated area that can be filtered. It also has a light level setting to 1 part in 65,535 in absolute, NIST-traceable, ANVIS radiance and luminance units.Gamma-Digital-Light-Source.jpg

It offers high resolution and digital brightness control that, according to the company, provides near-perfect linearity and uniformity, and it is designed to maintain the lowest uncertainty measurements possible.

It is also equipped with a manual control and a simple ASCII computer interface control via the company’s built-in RS-232 port.

A numerical value representing the degree of contrast in a television picture: the exponent of the power law used to approximate the curve of output magnitude vs. input magnitude over the region of interest.
The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
