Apart from wavelength measuring the SHR-IR provides demonstration of analysed spectra with resolution of 4 000 (λ/Δλ, FWHM) which constitutes from 0.15nm for 600nm to 0.5nm for 1800nm. The SHR-IR also ensures on-line monitoring of the above values in the process of tuning the analysed wavelength.

The instrument does not contain any moving elements; powering and control are performed from a computer via the Full-Speed USB interface. Analysed light is steered to the entrance slit either via a multimode optical fiber with a diffuse attenuator (included in the delivery set) or directly, without any fibers.

In respect of resolution and wavelength measuring precision the SHR-NIR is an alternative to a monochromator-spectrograph with focal length not less than 500mm, equipped with an appropriate IR-detector.

But unlike the monochromator, the SHR-NIR has no moving elements and provides real-time measurements without scanning. The SHR-IR is rigid, stable and accurate, ensures absolute reliability and has more reasonable price.

The SHR-NIR spectrometer is indispensable in the process of adjustment, alignment and testing of laser systems operating in the near IR spectrum range.
