SHR-IR - WavelengthMeter in the near IR range  近紅外波長光譜儀

SHR-IR 光譜儀是一款專為測量脈衝雷射與連續波(CW)雷射、以及雷射二極體的絕對波長而設計的理想儀器，涵蓋光譜範圍 600nm 至 1800nm。SHR-NIR 可偵測光譜線的半高全寬(FWHM)，解析度可達 4000 (λ/Δλ, FWHM)，對應於 600nm 時約 0.15nm、1800nm 時約 0.5nm。此外，SHR-NIR 還能在調諧過程中進行即時線上監測，即時掌握波長變化。

本儀器不含任何可動機械元件，其供電與控制均透過 Full-Speed USB 介面與電腦連線完成。被分析的光束可藉由多模光纖搭配漫射型衰減器(隨貨附贈)導入入射狹縫，或可直接耦合進入(不使用光纖)。在解析度與波長精度方面，SHR-NIR 可作為等效焦長不低於 500mm、搭配紅外線偵測器的單色儀–光譜儀的替代方案。但與傳統單色儀不同的是，SHR-NIR 無需掃描、無機械運動部件，即可進行即時量測。SHR-IR 結構紮實、穩定且精確，具有絕對可靠性，同時提供更合理的價格。SHR-NIR 光譜儀是近紅外雷射系統調整、校正與測試過程中不可或缺的工具。

The SHR-IR spectrometer is an ideal instrument for measuring absolute wavelength value of pulse and CW lasers and diodes in the spectral range 600nm-1800nm. The SHR-NIR allows detecting FWHM of the spectral line with resolution of 4000 (λ/Δλ, FWHM) which constitutes 0.15nm for 600nm to 0.5nm for 1800nm. The SHR-NIR also ensures on-line monitoring of the above values in the process of tuning the analyzed wavelength.

The instrument does not contain any moving elements; powering and control are performed from a computer via the Full-Speed USB interface. Analyzed 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 solid, stable and precise, 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.
