Ocean Optics Inc.
has expanded the wavelengths of its XR series miniature monolithic fiber optic spectrometers to cover from ~200 to 1050 nm. The newly developed XR-1 grating overcomes the challenges of providing broad UV-NIR coverage in a single device. It offers density of 500 lines per millimeter and is available preconfigured in the USB2000+, JAZ-EL2000 and USB4000 and can be added as an option to custom-built systems. The spectrometers deliver optical resolution of ~2 nm FWHM. A proprietary order-sorting filter is applied directly to the detector to eliminate second- and third-order effects. The 25-µm slit on the preconfigured units provides good optical resolution. The devices are suitable for setups that require both UV-VIS and VIS-NIR measurements and for measurement of samples with response across the entire wavelength range, such as solar irradiance, atomic emission line measurement and some plasma applications.
