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 reï¬ow soldering.
