Response Curve

 Built-in SiC UVB Detector designed to measure a broad range of light intensities emitted from solar simulators, broadband and narrow band UVB sources and UVB LEDs. This sensor can also be combined with ILT's SC280 blocking filter to further reduce the UVC levels measured by the detector for testing broadband sources with UVC emission.

Dynamic Range: 3e-7 to 5 W/cm²
Measurement Range: 275-320 nm
Dimensions: 3" x 3" x 1.25"
Ordering part #(s): ILT1270B/U, QT diffuser and PIR calibration at 290 nm.  (Other calibration options available).

Applications: Phototherapy, Solar UVB, UV LED, UV Radiation Measurements, Radiometry, UVB Transmission Testing, Aging, etc.


Note: For testing Narrow Band UVB sources such as TL-10 lamps and UV LED's, secondary calibrations can be performed at the peak/center wavelength of interest.  Please request XIR calibrations and specify the wavelength when requesting your quotation.



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