Response Curve


Measurement Range: 7e-8 to 1Watts/cm2
Spectral Range: 215 – 350 nm
Dimensions: 60 mm x 42 mm diameter

Order part number: ILT2400, SED270/QT includes PIR calibration at 270 nm (XIR calibration at 254nm, or SAR scanned calibration from 250-380 nm /every 2 nm are additional)

Applications: The Sic detector has broadband UV sensitivity allowing use for many applications. Since low-pressure mercury lamp and UV LED's typically emit a narrow spectrum, the ILT2400/SED270/QT can be used without additional filtration. (Calibration at the CW / peak is required for optimum performance).

Note: the QT is also available with 1, 3, 5 and 7 mm apertures for testing LED’s, small focused beams and for testing uniformity of the UV over the irradiated area. The apertures will also decrease the sensitivity allowing measurements at higher light levels.










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