Ocean Optics has expanded the wavelength capabilities of several of its popular miniature fibre optic spectrometers. The XR-Series, available for the USB2000+, JAZ-EL2000, and USB4000, covers all wavelengths from ~200-1050nm with the convenience and affordability of a single, monolithic spectrometer.
The new XR-1 grating option developed by Ocean Optics overcomes the traditional challenges of providing broad UV-NIR coverage in a single miniature spectrometer. With a 500 lines/mm density, the grating delivers high performance at a low price, without increasing the system footprint. The XR-1 grating is available pre-configured in the USB2000+, JAZ-EL2000, and USB4000 and may also be added as an option to custom-built systems.
The XR-Series spectrometers deliver an optical resolution of ~2.0nm (FWHM). Ocean Optics’ order-sorting filter is applied directly to the detector to eliminate second- and third-order effects. The 25µm slit on the preconfigured units delivers good optical resolution for most applications. XR-Series spectrometers are a convenient single-instrument solution for setups where both UV-VIS and VIS-NIR measurements are needed, and are well suited to measurement of samples with response across the entire wavelength range, such as solar irradiance, atomic emission line measurement and some plasma applications.
