SED033F LED Response Curve


Radiant Beam Intensity Detector: Detector with 9.27 mm aperture for measurement of radiant beam intensity in Watts/steradian.

Measurement Range: 2e-7 to 3 Watts/steradian
Spectral Range: 400 - 1064 nm
Order part number: ILT2400 (meter), SED033/F/LED (detector)


Applications: This detector is equipped with our Flat response correction filter designed to create a more uniform sensitive response in the VIS-NIR range. Typically used  for radiant beam intensity output of discrete LEDs, small LED modules, or small lamps with calibration for direct readings in  Watts/steradian). 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 and removed to allow placement over mounted LED's as shown in the sensor assembly photo.) 


SED SEL 033 Filter







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