Two-color detector
K12729-010K
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 reï¬ow soldering.
