SED033Y LED Response Curve

Photopic Power/Luminous Spherical Intensity Detector- Includes 5-Inch integrating sphere for measuring photopic power or luminous spherical intensity.

Measurement Range: 2e-2 to 2e+5 Lumens
Spectral Range: 400 - 700 nm
Order part number: ILT2400 (meter), SED033/Y/INS125 (detector with sphere, can also be used with ILT5000 Research Radiometer.)


5 inch sphere










Applications: This detector is equipped with our new Y Photopic filter designed using proprietary composite filter software to match the CIE V(λ) Photopic curve. Typically used for measuring higher power LEDs, LED modules, Fiber optic illuminators, Endoscopes and small lamps for photopic total flux output in Lumens. Can also be calibrated to measure luminous spherical intensity in Candela.


Note: Filters and input optics are removable. This sensor can configured with additional filters for total power measurements from 254-1000 nm as well as additional input optics including INS240N 10” sphere, Diffuser for lux/fc, and limiting apertures for spot uniformity testing.
