Ocean Optics has expanded the wavelength capabilities of several of its miniature fibre-optic spectrometers. The XR series, available for the USB2000+, JAZ-EL2000 and USB4000, covers all wavelengths from ~200 nm to 1050 nm.

The instruments deliver an optical resolution of ~2.0 nm with the company's order sorting filter applied directly to the detectors to eliminate second- and third-order effects. They are single-instrument solutions for set-ups 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.
