Two-color detector

K12729-010K

null

Wide spectral response range: 0.9 to 2.55 μm, Compact ceramic package

The K12729-010K is a two-color detector in a compact ceramic package, covering a wide spectral response range. Like the current K11908-010K, it incorporates two InGaAs PIN photodiodes with different spectral response, 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 dark current
-Supports reflow soldering
