The XD-45-HB BLUE Light Hazard Detector employs three filter sensors to cover the 300 to 700 nm spectral effectiveness range for BLH-Blue Light Hazard. A fourth photometric sensor is included to establish the 500 lux reference distance for illuminance and/or radiance qualification.
In addition the XD-45-HB-SRT200 radiance adapter is supplied for product qualification measurements of blue light hazard at the recommended distance of 200 mm. The adapter mounts onto the front of the XD-45-HB detector head and offers two exchangeable aperture plates to form a 100 mrad (20 mm diameter) and 11 mrad (2.2 mm diameter) field of view as stated in the IEC 62471 limit values.
The sensors are mounted into a compact housing that connects to the X1-3 meter via a two meter long cable. Calibration is certified traceable to national standards.
Another key feature of the X1-3 is its large capacity memory that can store calibration factors for all sensors and also source specific calibration correction factors for more than thirty UV, broadband and LED type sources. By selecting the appropriate correction factor (by menu function) from the light source library for the light source type under test measurement uncertainty is further improved.
