The QE
Pro
’s onboard module has 10 user-programmable digital I/O lines for interfacing to other
equipment; and a pulse generator for triggering other devices. You can use the I/Os to flash a lamp,
stop/start a process, and send a message/alarm during the spectrometer’s integration period. The
spectrometer’s operating parameters can be controlled through software. In fact, wavelength calibration
coefficients unique to each spectrometer are programmed into a memory chip right on the spectrometer.
The QE
Pro
’s high-speed electronics have been designed for considerable flexibility in connecting to
various modules and external interfaces, including PCs, PLCs and other embedded controllers, through
USB 2.0 or RS-232 communications.
A +5 VDC external power supply is required to operate the spectrometer. This power supply is included
with your spectrometer.
An optional internal shutter is available on custom-configured spectrometers (INTERNAL-SHUTTER-
LRG-BENCH). This makes it easier to take dark measurements and when you need fast integration times
with the best possible signal. This optional feature is also recommended for probe-based or emissive
measurements where it is difficult to introduce a shutter into the optical path. The shutter can be added to
an existing QE
Pro
for an extra charge.
Models
The QE Pro is custom configurable for your specific application. In addition, the following preconfigured
models are offered:

QE
Pro
-Raman
– for 785 nm Raman analysis with a wavelength range of 780 – 1100 nm (preset
for 785 Raman)
