Two-Color Detectors

Robust Dual-Wavelength Detection

Two-color, or “sandwich,” detectors are designed for applications that require extended spectral coverage or remote temperature measurement. These devices feature one photodiode stacked on top of another, using either the same or different semiconductor materials.

A wide range of standard and custom configurations is available, including combinations of silicon, germanium, InGaAs, and extended-wavelength InGaAs.
