Response Curve

Detector SED033/Y/R Luminance sensor designed for average measurement of luminance over a target area greater than 30 mm diameter plus 0.75 degree half angle. Field of view: 1.5 deg. Includes the Y2 photoic filter which was redesigned using proprietary composite filter design software to match the CIE V(λ) Photopic curve within 1% total area error.


Dynamic Range: 6e-3 to 1e+7 cd/m2
Measurement Range: 400-700 nm
Dimensions: 90 x 42 mm dia.
Ordering part#(s): ILT5000, SED033/Y/R
* Software Included / Tablet PC Sold Separately









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

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