The SNAPSCAN portable hyperspectral imaging system adopts IMEC's unique pixel coating spectroscopy technology, which changes the spectral mode that traditional hyperspectral instruments require slits and gratings. Compared with traditional hyperspectral instruments, it has a small volume, high spectral efficiency, fast hyperspectral data acquisition speed, and can obtain hyperspectral cube data up to 2 seconds. It has a built-in refrigeration system, which can obtain high signal-to-noise ratio hyperspectral data. Due to the use of a large array detector, the system can achieve a spatial resolution of up to 2048 x 3650, with about 150 spectral channels. The system transmits data through the USB3.0 interface, which is easy to operate, flexible to configure, and is a portable, high-resolution, and cost-effective set. A cost-effective spectral imaging instrument. It can be applied in high-altitude remote sensing, field spectral imaging target recognition, indoor hyperspectral imaging detection, and microscopic spectral imaging.
