Two-color detector

K13085-010K

null

Two InGaAs PIN photodiodes with different wavelength regions have been installed above and below to provide a wide spectral response range

The K13085-010K is a two-color detector with two InGaAs PIN photodiodes with different cutoff wavelengths installed along the same optical axis. It provides a wide spectral response range, and it makes optical system design easy because its photosensitive areas is along the same optical axis.


Features
-Two InGaAs PIN photodiodes with different cutoff wavelengths are installed along the same optical axis
-Low noise
-Low dark current
