Spectral Imaging (Specim) has extended its ImSpector Enhanced series of imaging spectrographs with high-resolution imaging Raman spectrographs. The drive for the development of the Raman imaging spectrograph came from the need for combining high light throughput, distortion-free performance, and polarisation-free optical design. All these main requirements, together with the required small footprint of the device, good image quality, and high spectral resolution, were achievable with the fully-transmissive optical design used in the Specim ImSpector series of imaging spectrographs. By combining the Raman ImSpector with a sensitive CCD camera, optimised objective lens, and required excitation line-laser, Specim customers are able to construct an imaging Raman measurement system. The imaging Raman spectrographs are available for several standard wavelength ranges from 500nm to 1000nm for use with different types of excitation laser.
Specim states that its ImSpector series feature a favourable performance-to-cost ratio, which has made the series popular among both industrial OEM customers and scientists who integrate their own hyperspectral imaging solutions. The ImSpector imaging spectrograph is a component that can be integrated with an monochromatic camera to form a complete spectral imaging device that captures line images of a target and disperses each line image pixel into a spectrum. Consequently, ImSpector allows diverse opportunities to analyse accurately the spatial distribution of target properties based on its spectral features.
