Ocean Optics - HR2000+CG High-Speed, Broadband Spectrometer

Features

Wide range (200-1050 nm) broadband spectrometer

High resolution (1.0 nm FWHM) over the entire 200-1050 nm spectral range

Programmable microcontroller

Works with SpectraSuite Spectrometer Operating Software

200-1050 nm Range, 1.0 nm Resolution

The HR2000+CG Spectrometer utilizes a 5 µm entrance slit, proprietary HC-1 grating and patented order-sorting filter to provide a 200-1050 nm wavelength range and excellent optical resolution (1.0 nm FWHM). This spectrometer combines the "HR" optical bench with the Sony ILX511B 2048-element detector for excellent resolution and high speed. The OFLV-200-1050 order-sorting filter is installed to eliminate second- and third-order effects.

Composite-grating & Variable Order-sorting Filter

The HR2000+CG uses the HC-1 grating, which is a revolutionary and proprietary variable blazed grating designed to provide a 200-1050 nm wavelength range. (See the grating efficiency curve for the HC-1 at right.) In addition to this composite grating, each CG-series Spectrometer has an OFLV variable longpass order-sorting filter to eliminate second- and third-order effects. Both the grating and OFLV filter are installed at the time of manufacture and are fixed in place.

Programmable Microcontroller

The HR2000+CG has an onboard programmable microcontroller that provides flexibility in controlling the spectrometer and accessories. By using a new 30-pin connector, you can implement numerous operating parameters in the software, including controlling external light sources and retrieving data on external objects. You have access to 10 programmable digital I/Os for interfacing to other equipment; one analog input and one analog output; and a pulse generator for triggering devices.
