SED033Y LED Response Curve

Luminous Beam Intensity Detector:  Detector includes an H2 Hood to block ambient light and easily establish the working distance for measurement for LED's and small light sources 

Measurement Range: 4e-6 to 391 cd
Spectral Range: 400 - 700 nm (< 1% total area error to CIE)
Order part number: ILT2400, SED033/Y/H2 (detector)

Applications: This detector is equipped with our photopic correction filter designed using proprietary composite filter software to match the CIE V(λ) Photopic curve within 1% total area error. Typically used  for luminous beam intensity output of discrete LEDs, small LED modules, or small lamps with calibration for direct readings in Candela (Candlepower). Note (aperture was increase to 9.27 mm 6/17.)  The aperture is used to block ambient light and align the LED.  It can be unscrewed to remove to allow placement over mounted LED's as shown in the sensor assembly photo.

Beam Insensity


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