SED033 TBLU SCS TD Response Curve

BLUE LIGHT HAZARD DETECTOR Specially configured for blue light hazard measurements with conformance to the human eye stimulation requirements with direct reading of  irradiance in W/cm2.  The SED033/BLUE/TD includes a 33 mm2 active area Si sensor, with a ½ inch BLUE filter, domed teflon diffuser for improved cosine response and irradiance calibration at 450 nm.

Measurement Range: 9e-9 to .1 W/cm2
Blue Hazard Spectral Range: 390-510 nm
Order part number: ILT2400 (meter), SEL033/BLUE/TD


Applications: This detector was designed to conform to the human eye stimulation requirements for making blue light hazard measurements from Welding source, Pulsed blue lights used in curing or disinfection, LED and/or testing most other blue light sources.  Calibrated to measure irradiance (light reaching the sensor surface) directly in W/cm2.


ILT SED Filter










Filters and input optics are removable and may be ordered separately from the detector assembly to allow filter and input optic swapping.
