Gamma Scientific has launched the RS-5NVIS digital light source to test and calibrate ANVIS radiometers and spectroradiometers.
It offers high resolution and digital brightness control that provides near-perfect linearity and uniformity and maintains low uncertainty measurements.
It 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 RS-5 digital light source, which has a feedback-stabilised LED optical head with a diffusely illuminated area that can be filtered.
It 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 per cent RMS of full scale over the entire brightness adjustment range.
It delivers 100 times the previously available light source lifetime and the lamp rarely, if ever, needs changing, resulting in nearly zero downtime.
The RS-5NVIS is equipped with a manual control and a simple ASCII computer interface control via the built-in RS-232 port.
