The USB4000 plug and play spectrometer
The USB4000 is the world‘s most popular
spectrometer…And there is a reason!
The USB4000 is a powerful, rugged, utilitarian
instrument which is highly cost effective. The
USB4000 has been used for literally tens of
thousands of various optical and spectral
sensing tasks. The
design includes an advanced detector
array plus powerful high speed electronics.
The detector array is a 3648 pixel
array for excellent spectral resolution and
the electronics provide a 300:1 signal to
noise response. There is a 16 bit A/D,
four triggering options, a dark current
correction features and a 22 pin connector
with eight user programmable GPIOs.
Also, with the operational software, SpectraSoft,
USB4000 spectrometers can be
operated with computers having Windows,
Linux and Mac operating systems.
Operation of the USB4000 can be noted
by referring to the cut-away diagram.
- Fiber input line brings the signal into the spectrometer.
- Entrance slit whose size can be specified.
- An optional filter
- Collimating mirror
- Grating where wavelength range can be factory adjusted
- Focusing mirror
- Optional detector collection lens may be installed
- Detector array
- OFLV order sorting filter if used
- Upgrade to extend the detector response into the UV
These parts combine to make a highly
effective spectrometer.

Spectrometer variations
Choosing the spectrometer that's
right for the task usually depends upon
the range and resolution needed. Typically,
such a choice is based upon the
slit size (resolution), the grating
(spectral range) and what detector is
better. Also the availability of various
options can provide a user with great
flexibility. Spectral ranges start at 210
nm and can extend toward 1100 nm.
In a trade-off between range and
resolution, a USB4000's range can be
maximized with a typical resolution of
~1½ nm. Whereas, if a high resolution
near ½ nm is wanted to better view a
certain part of the spectrum, a shorter
range, say about 200 nm, will result.
For assistance in defining range and
resolution, send an E-mail enquiry to
Ancal with the needs specified.
Often it is better to choose a preconfigured
USB4000 spectrometer. There
are two preconfigured USB4000 spectrometers,
one of which may be right
for a user. The USB4000-UV-VIS is
preconfigured with a UV detector upgrade
to cover the spectral range from
200 nm to 850 nm with a nominal
resolution of 1.5 nm; the USB4000-VIS-NIR
is preconfigured to cover the
spectral range from 350 nm to 1000
nm with a nominal resolution of 1.5
nm. These two spectrometers provide
users with standard responses plus the
convenience of "off-the-shelf" ordering.
Also, by choice of various input
accessories, these spectrometers can be
applied to measuring tasks as different as
absorbance measurements and color
reflectance determinations.
