950–1700 nm Miniature NIR Spectrometer

The 950-1700 nm miniature NIR spectrometer is an ultra-compact near-infrared spectral module designed for portable detection and OEM integration applications. The product uses a high-efficiency transmission grating and an uncooled InGaAs linear array detector, covering the 950-1700 nm near-infrared band, with a typical spectral resolution up to 9.5 nm and a numerical aperture of NA 0.22. The overall dimensions are only 23 × 21 × 8 mm, and the weight is less than 5 g. It combines high sensitivity, low stray light, and good environmental stability. It supports free-space or SMA fiber input, as well as SPI/USB 2.0 communication, making it particularly suitable for integration into handheld, portable, and miniaturized near-infrared analysis devices.
