Light Hazard Meter from Gigahertz-Optik
January 20, 2013
The X1-3 light hazard meter from Gigahertz-Optik Inc., Newburyport, MA, is a field-portable filter radiometer for testing the photobiological safety of lamps and lamp systems. ANSI/IESNA RP-27.2-00, IEC/DIN/EN/ 62471 (CIE S 009), and DIN EN 14255-1 standards added the ability to use filter radiometers, with some restrictions, as an alternative measurement method to the spectroradiometric method. The meter with the XD-45-HUV UV hazard detector, XD-45-HB blue light hazard detector, and XD-45-HB-SRT200 FOV and distance adapter fulfills this requirement for product classification and light hazard assessment. The meter can operate and read out the two separate multisensor/filter detectors required.
