HR2000+ES High-resolution Spectrometer
 for Enhanced Sensitivity
The HR2000+ES Spectrometer
is a preconfigured system that integrates
a high-resolution optical bench,
a powerful 2-MHz
analog-to-digital (A/D) converter, programmable
electronics, a 2048-element CCD-array
detector, and a high-speed USB 2.0 port. This
innovative combination produces and extremely fast spectrometer and
provides resolution to ~1.33 nm (FWHM).
The HR2000+ES has a slightly larger
entrance slit (10 microns) and an L2 quartz collection lens to allow for
extended measurement applications including:
- Reflection (emissive and reflective color)
- Absorbance
- Irradiance
- Transmission
The HR2000+ES is perfect for chemical,
biochemical and other applications where fast reactions need to be
monitored and fine spectral features need to be resolved.
The HR2000+ES has an onboard programmable microcontroller
that provides flexibility in controlling the spectrometer and accessories.
Through a new 30-pin connector, you can implement all operating parameters
in the software, such as controlling external light sources, creating
processes and routines and retrieving data from external devices. The
HR2000+ES gives you access to 10 user-programmable digital I/Os for
interfacing to other equipment; one analog input and one analog output;
and a pulse generator for triggering other devices. (Programming the I/Os
requires SpectraSuite Spectroscopy Operating Software.)
The HR2000+ES is ideal for applications where fast
reactions need to be monitored and high resolution is necessary, such as
protein dynamics.

| This power-up data for our LS-1 Tungsten Halogen
Light Source was taken by an HR2000+ at 2-millisecond intervals. The
graph shows the tremendous amount of data generated with the HR2000+’s
acquisition rate speed of 1000 spectra per second. |
The exceptional ~1.33 nm optical resolution of the
HR2000+ES is achieved by using the Ocean Optics High-resolution Optical
Bench – a 25.4-mm diameter, 101.6-mm focal length, symmetrical crossed
Czerny-Turner optical design.
The HR2000+ES interfaces to a computer via USB 2.0 or
RS-232 serial port. When using the serial port, the HR2000+ES requires a
single 5-volt power supply (not included). Data unique to each
spectrometer are programmed into a memory chip on the HR2000+;
SpectraSuite Spectrometer Operating Software reads these values for easy setup and hot
swapping among computers.
