Description
The DragonFly (DF) Series spectrometers feature advanced digital light processing (DLP) technology, utilizing a programmable digital micro-mirror device (DMD) chip paired with a high-sensitivity Hamamatsu G12180 series 1 mm InGaAs photodiode.
The Hadamard scan mode enhances signal-to-noise ratio by up to 2–7× compared to standard column scanning. A 32-bit ARM Cortex-M4F RISC microcontroller provides fast processing and precise system control.
Powered via USB or UART, the DF Series offers models with optional TEC cooling, exposed circuit boards, or protective housings for flexible OEM and laboratory integration. Covering 900–2280 nm, the DragonFly Series delivers exceptional performance for demanding near-infrared applications.
