SED033Y LED Response Curve

Photopic Power/Luminous Spherical Intensity detector includes 10-Inch integrating sphere for measuring photopic power or luminous spherical intensity 
Measurement Range: 5e-6 to 8e+3 Lumens

Spectral Range: 400 - 700 nm
Order part number: ILT5000*, SED033/Y/INS250 (detector)
* Software Included / Tablet PC Sold Separately


Sphere detector











Applications: This detector is equipped with our Y filter designed using proprietary composite filter software to match the CIE V(λ) Photopic

curve within 1% total area error. Sphere is equipped with built-in lamp permitting absolute calibrations even with variations introduced by a variety of test items. Typically used for measuring higher power LEDs, LED modules, and small lamps for photopic total flux output in Lumens. Can also be calibrated to measure luminous spherical intensity in Candela (Candlepower).

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


For simultaneous multi-sensor data logging, ILT also offers the ILT6000 with the same specifications as the ILT5000 in a 2-10 unit, rack mountable housing.
