SED SEL 185NS Response Curve

NARROWBAND OZONE/GERMICIDAL DETECTOR Configured to measure low intensity, ozone producing germicidal lamps at 185 nm where out of band rejection of 254 nm is critical.

Measurement Range: 2e-5 to 3e-1 Watts/cm2
Spectral Range:165 – 200 nm, Center wavelength: 185 nm
Order part number: ILT2400 (meter), SED185/NS185 (detector)

Applications: This detector by itself has peak spectral response at 185 nm but has also been fitted with a narrow bandwidth filter facilitating the measurement of the relatively low emissions at 185 nm from ozone producing mercury lamps with strong emissions at the 254 nm mercury line.
