Description
The PocketHawk (PH) Series spectrometers combine compact design with high optical performance, utilizing a Crossed Czerny–Turner optical system for excellent resolution, sensitivity, and low stray light. Equipped with a linear CCD or CMOS sensor (UV-Vis) or an InGaAs sensor (NIR) and a 32-bit RISC controller, the PocketHawk is engineered for miniaturization and seamless system integration. The simplified optical engine and external MB-type casing enhance thermal management and stability, while programmable digital I/O and USB connectivity enable easy integration into OEM and laboratory platforms. Powered entirely by USB, the PH Series supports fast spectral acquisition, calibration coefficient storage, and plug-and-play operation for a wide range of UV-Vis and NIR applications.
