Specim Spectral Imaging, a manufacturer of hyperspectral imaging systems, has extended its Imspector Enhanced series of imaging spectrographs with high-resolution imaging Raman spectrographs.
These are intended to meet a need for a combination of high light throughput, distortion-free performance and polarisation-free optical design.
The company claims that these requirements, together with a small footprint of the device, good image quality and high spectral resolution, were possible to achieve with the fully transmissive optical design used in the Specim Imspector series of imaging spectrographs.
By combining the Raman Imspector with a sensitive charged-coupled-device (CCD) camera, an optimised objective lens and a required excitation line laser, Specim customers can now construct an imaging Raman measurement system.
The imaging Raman spectrographs are available for several standard wavelength ranges from 500nm up to 1,000nm for use with different types of excitation lasers.
The Imspector imaging spectrograph is a component that can be integrated with an area-monochrome 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 is said to allow opportunities to accurately analyse the spatial distribution of target properties based on spectral features.
