The R1477-06 has a high sensitivity multialkali photocathode (even
higher than the R928). 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 oth-
er low light level applications requiring super-high cathode sensitivity
from the UV to the near IR regions of the spectrum.
