Description
The DragonFly (DF) Series spectrometers utilize advanced DLP technology, featuring a DMD chip and single-photon InGaAs photodiodes. This combination achieves high optical efficiency, pixel density, and miniaturization. The programmable DMD enables flexible scan modes and reduced scanning time, while Hadamard mode greatly enhances signal-to-noise ratio (SNR). Powered by USB or UART, the DF Series is available with exposed circuit boards or protective casing options. Models cover a wide range of near-infrared wavelengths and offer robust performance for demanding applications.
