LTB Lasertechnik Berlin provides the Double
Echelle Monochromator Demon. The Demon
combines very high spectral resolution,
high optical throughput and a short readout time of the detector due to on-chip
binning. Its patented optical design with premonochromator and echelle grating gives the
user the capability of resolutions up to 150.000
(4pm @600nm). In contrast to interferometric
testing systems the Demon enables the user
to monitor the spectral bandwidth, intensity
profile and absolute wavelength simultaneously.
The large inspection range of the Demon
allows monitoring the main mode together
with the side modes. Thus the Demon is the
ideal instrument to characterise the complete
emission behaviour of the diode laser.

and allow for a more compact
range finder design. The design
can withstand high acceleration
rates of over 1000g/ms and can
withstand high temperatures of
up to +85ºC. This technology is
also available with 905nm pulsed
laser diodes and if the wavelength
has to be controlled exactly a
thermoelectric cooler (TEC) can
be integrated into the housing.

iFLEX-Gemini includes
kineFLEX technology that has
long been used in biomedical
and metrology applications
requiring high power throughput
and ultra-stable beam pointing.
Now iFLEX-Gemini is enabling
more applications including
new leading edge point of use
analysers for forensics and
remote sensing.

Laser Components’ HI-Series
feature a divergence of 25 x
12 degrees compared to the
industry standard of 12 x 30
degrees for a higher intensity
output ready for pin-for-pin
replacement. The HI-FAC-Series
is the result of combining these
high performance HI-Series
with a Fast Axis Collimator lens
mounted directly in front of
the laser diode chip inside the
hermetic TO-can. A divergence
of 5mrad is achieved depending
on the lens used resulting in
12 degree x 5mrad divergence
which can save engineering costs

Qioptiq has expanded its
range of iFLEX-Gemini lasers
to include additional pairings
like 405nm and 660nm, plus
488nm and 640nm. The
iFLEX-Gemini dual diode laser
system is compact, low noise,
has low power consumption
and dual-wavelength collinear
output enabling researchers and
manufacturers to innovate their
approach to laser illumination
to achieve smaller instruments,
performance improvements and
cost savings. Novel architecture
allows both wavelengths in the
iFLEX-Gemini to be controlled
independently, CW or directly
modulated. The singlemode,
linearly polarised fiber output
from the iFLEX-Gemini can be
provided with connectors such as
FC, APC, FCP8, or alternatively
with a collimated or focussed
