Two-color detector
K12728-010K
Wide spectral response range: 0.32 to 1.65 μm, Compact ceramic package
The K12728-010K is a two-color detector in a compact ceramic package, covering a wide spectral response range. Like the current K1713-09, it incorporates an infrared-transmitting Si photodiode mounted over an InGaAs PIN photodiode, along the same optical axis. It features low noise and low dark current and supports reflow soldering.
Features
Wide spectral response range Compact, low noise, low.
