InGaAs Quad Arrays

Teledyne Judson’s InGaAs quad arrays offer four-channel detection in a compact format, ideal for simultaneous multi-point measurements. With high quantum efficiency and low noise, these arrays are well-suited for Raman spectroscopy and optical sorting, where spatial resolution and parallel data capture are essential.
