Our HR4000CG Composite-grating (CG) Spectrometer uses our HC-1 Grating -- a revolutionary and proprietary variable-blazed grating specifically designed to provide full spectral output throughout the 200-1100 nm range, with best efficiency at 200-1050 nm. The revolutionary HR4000CG is a preconfigured HR4000 Spectrometer with all of the optical bench options already selected for you. This turn-key system is immediately available to you as an off-the shelf purchase for $5774. |
Wide range (200-1100 nm) broadband spectrometer
High resolution (0.75 nm FWHM)
Installed HC-1 composite grating and order-sorting filter
Works with SpectraSuite Spectrometer Operating Software, available for $199
The HR4000CG Spectrometer utilizes a 5 µm entrance slit, proprietary HC-1 grating and patented order-sorting filter to provide a 200-1100 nm wavelength range and excellent optical resolution: 0.75 nm (FWHM). The HR4000CG comes with a 3648-element linear-array CCD detector that not only provides better optical resolution throughout the 200-1100 nm range, but also provides improved sensitivity in the 1070-1100 nm region. The HR-series Spectrometers use the “HR” Optical Bench and come with UV Detector Upgrades to enhance the performance of the spectrometers in the UV.
All
CG-series
Spectrometers use the HC-1 grating, which is a revolutionary and
proprietary variable blazed grating designed to provide a 200-1100
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.
The HR4000CG 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.
