GENERAL OVERVIEW
THE LOWEST-NOISE DRIVER
AVAILABLE
These low noise QCL instruments have the lowest current
noise density of any commercially available. Powering your
QCL with this patented
1
driver gives you narrow linewidth,
stable center wavelength, and repeatable scans.
INTUITIVE USER INTERFACE AND
SUPERIOR SOFTWARE CONTROL
With Wavelength’s plug and play instrument, you have the
ability to quickly set the controls using either the instrument or
a remote computer.
PROTECT YOUR QCL INVESTMENT
All the essential control and monitor functions you expect in a
Wavelength laser driver are incorporated into this instrument,
along with protection circuitry to safeguard your QCL from
minor power source faults, over-temperature conditions, and
electrical faults.
The soft-clamping current limit can be set without enabling the
driver output, and uses a brick-wall never-exceed limit circuit
to protect the QCL from potentially damaging overcurrent
situations.
OEM VERSION AVAILABLE
Once you have fi nalized your work, the QCL circuitry is
available in compact OEM versions.
APPLICATIONS
Due to their unique construction, QCLs operate with high
power in the near-IR through terahertz ranges. These
wavelengths are particularly suited to detection of molecules
signifi cant to humans.
Applications for the lower noise QCL driver include: remote
detection of explosive materials, medical diagnosis using the
breath, non-invasive glucose testing, emissions monitoring of
the atmosphere or marine environments, and pharmaceutical
process quality control. Additional applications include
anesthesia and hospital air quality monitoring, leak detection,
and remote imaging.
