Hand-Held Illuminance /Luminance Meter


SED033/Y4/L30-1 Illuminance sensor is a versatile visible light sensor that can be calibrated to measure lux, foot-candles,candela, effective candela and luminance in Foot-lamberts, cd/m2 or Nits.  The Silicon based sensor is photopically corrected with our multilayer Y4 photopic correction filter and the L30-1 high gain lens that increases the signal 30 times for low light level measurements.  The lens has a +/- 8 degree field of view making it an excellent choice for luminance measurements as well as effective candela measurement at distances over 25 feet.
 

Measurement Range: 

Illuminance: 3e-4 to 3e+3 lux plus the factor for cd of a continuous source at any distance
Luminance: 5e-3 to 4e+4  fL
Spectral Range: 400-700 nm CIE human eye response
Dimensions:51 x 42 mm dia.
Ordering part#(s): ILT2500, SED033/U, Y4, L30-1, and YIS calibration for Illuminance and/or YLS calibration for Luminance.
