The SHR-IR spectrometer is an ideal instrument for measuring absolute wavelength value of pulse and CW lasers and diodes in the spectral range from 600 nm to 1800 nm with accuracy better than ± 15 pm, as well as detecting FWHM of the analyzed line.

Apart from wavelength measuring the SHR-IR provides demonstration of analysed spectra with resolution of 4000 (λ/Δλ, FWHM) which constitutes from 0.15 nm for 600 nm to 0.5 nm for 1800 nm. 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 500 mm, 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.
