USB4000-UV-VIS Miniature Fiber Optic
 Spectrometer
The USB4000-UV-VIS is preconfigured for applications from 200-850
nm. The USB4000-UV-VIS features a 3648-element Toshiba linear CCD array
for increased signal-to-noise and enhanced electronics for
controlling the spectrometer and accessories.
--Available for immediate delivery! --
Features
The USB4000-UV-VIS Spectrometer is
pre-configured with the DET4-200-850 detector and order-sorting filter
to cover the 200-850 nm wavelength range. The spectrometer comes with a
multi-bandpass order-sorting filter and a 25 µm entrance slit
for optical resolution to ~1.5 nm (FWHM).
Programmable Microcontroller
The USB4000-UV-VIS onboard programmable microcontroller provides you with
considerable flexibility in controlling the spectrometer and accessories.
Through a 22-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 8 user-programmable
digital Inputs/Outputs for interfacing to other equipment. (Contact an Applications Scientist regarding what you'll need to
program the GPIOs.)
Optimal
Performance
The USB4000-UV-VIS provides you with an affordable, high-performance 3648-element linear CCD-array
detector with an optical bench that's small enough to fit into the palm of
your hand. The USB4000-UV-VIS works the same way as other Ocean Optics spectrometers; it accepts light energy transmitted through single-strand optical
fiber and disperses it via a fixed grating across the linear CCD array
detector, which is responsive from 200-1100 nm.
Modular Design
When you purchase a
USB4000-UV-VIS,
you can also choose from Ocean Optics'
complete line of spectroscopic accessories. Most
accessories have SMA 905 connectors for application flexibility. Changing the
sampling system is as easy as unscrewing a connector and adding new
components or accessories, such as light sources, sampling holders, filter
holders, flow cells, fiber optic probes and sensors, collimating lenses,
attenuators, diffuse reflectance standards, integrating spheres and our
extensive line of optical fibers.
Plug and Play Operation
The USB4000-UV-VIS interfaces to a PC, PLC or other embedded controllers via USB 2.0
or RS-232 serial port. When using the serial port, the USB4000-UV-VIS
requires a single 5-volt power supply (not included). Data unique to each
spectrometer is programmed into a memory chip on the USB4000; our
spectrometer operating software reads these values for easy setup and hot
swapping among PCs.
Serial
port operation tips: When using the serial port, the USB4000-UV-VIS
requires a single 5-volt power supply (not included). Also, SpectraSuite
Spectroscopy Software does not support spectrometer operation via the
serial port. However, using the included Serial Port Command Set, you
can write your own software that makes serial port operation possible.
