The HR2000+ Spectrometer
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 0.035 nm
(FWHM). The HR2000+ allows users to capture and store a full
spectrum into memory every millisecond (that's 1,000 full
spectra every second) when the spectrometer is interfaced to
a computer via a USB 2.0 port. The HR2000+ is perfect for
chemical, biochemical and other applications where fast
reactions need to be monitored and fine spectral features
need to be resolved.
1,000 Full Spectra/Second
The HR2000+ utilizes an onboard, 2-MHz A/D converter, which
allows you to capture and transfer one full spectrum into
memory every millisecond when the spectrometer is interfaced
to a PC via the USB port.
Programmable Microcontroller
The HR2000+ 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+ 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.)
High-resolution Applications
The HR2000+ is ideal for applications where fast reactions
need to be monitored and high resolution is necessary, such
as protein dynamics. For solution chemistry or color
measurements, the USB4000 is more likely to fill your
requirements.
High-resolution "HR" Optical
Bench
The exceptional 0.035 nm optical resolution of the HR2000+
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+ is responsive from 200-1100 nm, but its specific
range, resolution and sensitivity depend on your “HR”
Optical Bench options. You select the grating, wavelength
range, mirror coating, detector window and entrance aperture
size. Choose from hundreds of accessories to create
application-specific systems.
Plug and Play Operation
The HR2000+ interfaces to a computer via USB 2.0 or RS-232
serial port. When using the serial port, the HR2000+
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.
Optical Bench Options
At Ocean Optics, we understand that your work is unique and
that you want a spectrometer to fit your specific needs.
With the HR2000+ Spectrometer, you can configure the bench
for your application. Choose HR2000+ Optical Bench Options
such as entrance aperture size, detector accessories,
filters a grating and more. Our application scientists will
help you determine which configuration will best work for
you.
