FIGSPEC FS2X Series Imaging Hyperspectral Cameras

Description

FigSpec® series of imaging hyperspectral cameras adopt transmission grating splitter module with high diffraction efficiency and high sensitivity surface array camera, combined with built-in scanning imaging and auxiliary camera technology, which solves the difficult problems of traditional hyperspectral cameras, such as external push scan imaging mechanism and complex focus. It can be directly integrated with standard C interface imaging lens or micro-scope to achieve rapid spectral image acquisition.

Applications

FS-25 microscope to measure MSU

Using the FS-25 and a microscope, we analyzed stained MSU crystals and
identified their unique spectral characteristics. These distinct features enabled us to locate MSU crystals in unstained pathological sections.

FS-25 Anti-counterfeiting Identification

Using the FS-25, we analyzed the recognition of camouflage clothing against surrounding green environments for anti-counterfeiting. Results showed similarities and differences in spectral waveforms around 1600nm. Identification was performed through modeling based on distinct spectral features.

FS-25 DUI test

Using the FS-25, we tested for alcohol gas in a laboratory with beakers and
conducted non-contact testing in vehicles. Results showed a distinct downward absorption peak at 1402nm for alcohol gas in both lab and outdoor settings. This method is suitable for non-contact online detection in parking lots and entry/exit points.

FS23 Flame Analysis

Using the FS-23, we tested plasma flames to assess temperature variations. The results revealed distinct signal strengths corresponding to different temperature levels in the flames.
