The spectral response covers a wide range from 185 to 900 nm with a peak response at approximately 450 nm. The R1477-06 also features the combination of high gain and low dark current. The R1477-06 is recommended for use in spectrophotometry and other low light level applications requiring super-high cathode sensitivity from the UV to the near IR regions of the spectrum.
