SED240W Response Curve


Configured to measure low intensity, low-pressure mercury lamps for 254 nm output (see sensor spectral response curve) as well as UV LED's used for sterilization / germicidal applications.

Measurement Range: 1.00e-9 to 5.00e-4 Watts/cm2

UV Actinic Hazard Spectral Range: 185 – 320 nm, calibration wavelength at 254 nm (other calibration wavelengths are available)

Dimensions: 60 mm x 42 mm diameter

Order part numbers: ILT5000*, SED240/W (detector)
* Software Included / Table PD Sold Separately

Note:  SED240/W detector also works with the ILT2500 Flash Meter



SED240 Cosine Response Graph

This detector has a peak spectral response at 254 nm and is designed to measure low-intensity, narrowband sources with output in 254 nm range. Since low-pressure mercury lamps produce better than 95% of their energy at 254 nm, no bandbass filters are needed. When used with UVC LED's, calibration at peak wavelengths are also available.

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



Note:  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.
