SED240W Response Curve


Configured to measure low intensity, low-pressure mercury lamps only.

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

UV Actinic Hazard Spectral Range: 185 – 320 nm, calibration wavelength at 254 nm

Dimensions: 60 mm x 42 mm diameter

Order part numbers: ILT1700 (meter), SED240/W (detector)

Applications: This detector has a peak spectral response at 254 nm and is designed to measure low-intensity, low-pressure mercury sources only. Since low-pressure mercury lamps produce better than 95% of their energy at 254 nm, they are easily measured by this detector without additional filtration.
