A standard brightness source (standard brightness generator) is a set of standard sources that provide uniform and stable brightness (radiance). It has the advantages of good brightness uniformity, large brightness adjustment range, high stability, easy use, and adjustable output current. Mainly used in the calibration and verification of equipment such as photometers, telescopes, image sensors, photometers, radiometers and electronic images.
1) Brightness: 0-1000cd/m2 adjustable
2) Color temperature: 2856K±25K
3) Brightness stability: ±0.5%
4) Brightness non-uniformity: <1.5% (not counting near the edge)
5) Light outlet: Ï200mm
6) Brightness uncertainty: ±5%
7) With fully digitally controlled DC stabilized Voltage and current power supply, Voltage and ammeter accuracy: ± (0.03% reading + 0.01% range + 1 word)
