HR4000 High-Resolution Spectrometer
 Our next-generation
high-resolution spectrometer is a novel combination of optics and
electronics that is ideal for applications such as characterizing lasers,
measuring gas absorbance, and determining atomic emission lines. The
HR4000 is available for beginning at $4619.
The HR4000 Spectrometer is our next-generation
high-resolution spectrometer. The HR4000 has a 3648-element CCD-array
detector from Toshiba that enables optical resolution as precise as 0.02
nm (FWHM). The HR4000 is responsive from 200-1100 nm, but the specific
range and resolution depend on your grating and entrance slit choices.
This novel combination of optics and electronics is ideal for applications
such as characterizing lasers, measuring gas absorbance, and determining
atomic emission lines.
Integration Time is a setting in our software that
is specified by the user. It’s analogous to the shutter speed of a
camera: the value specified for the integration time is the amount of
time the detector “looks” at the incoming photons. Because the Toshiba
detector has an electronic shutter, you can specify, via software,
minimum integration times as short as 3.8 milliseconds, which allow
you to measure transient events like laser pulses (for even faster
integration times using the External Hardware Trigger Mode, see our
HR2000+ Spectrometer). Also, the ability
to integrate the spectrometer for short durations eliminates
saturation problems that can occur in high light-level applications
such as laser analysis.
The HR4000’s onboard microcontroller provides you with
considerable flexibility in controlling the spectrometer and accessories.
Through a 30-pin connector, you can implement all operating parameters in
the software: control light sources, create processes, and retrieve
information on external objects. You have access to 10 user-programmable
digital inputs/outputs for interfacing to other equipment; one analog
input and one analog output; and a pulse generator for triggering other
devices. (Programming the GPIOs requires SpectraSuite, OmniDriver or one
of our other device drivers.)
When purchased with the Remora Network
Adapter users can communicate with the HR4000 over
Ethernet or Wi-Fi. Use with SpectraSuite
Software, and turn your device
into a network accessible
spectrometer. Remotely capture
spectral data from anywhere Plus, Remora
allows multiple users to access
data and experiment settings
without the need for additional
equipment. Remora's
web-interface works with all popular web browsers and allows you to
monitor data from a PDA, iPhone, and most internet ready devices.

The HR4000 interfaces to a computer via USB 2.0 or
RS-232 serial port. When combined with
the Remora Network Adapter, the USB interface allows you communication
via Ethernet and/or wireless network. When using the serial port, the HR4000 requires a
single 5-volt power supply (not included). Data unique to each
spectrometer are programmed into a memory chip on the HR4000; our
SpectraSuite Spectroscopy
Operating Software reads these values for easy setup and hot swapping
among computers, whether they run on Linux, Mac or Windows operating
systems.
At Ocean Optics, we understand
that your work is unique and that you want a spectrometer to fit your
specific needs. With the HR4000 Spectrometer, you can configure the bench for your application.

will
help you determine which configuration will best work for you.
Our
HR4000 Manual provides you with instructions for setting up,
calibrating and performing experiments with your HR4000 spectrometer.
The
HR4-BREAKOUT is a passive module that provides
access to a variety of functions found in the HR4000. The BREAKOUT BOX
allows multiple interfaces to a spectrometer such as: external triggering, GPIO, light sources, RS-232 interface and analog input/output.
