Photron USA Inc.’s high-defini-tion, high-speed Fastcam SA6
camera is suitable for use in
automotive, military, broadcast,
particle velocimetry and digital
image correlation applications.
It is available in 36-bit color and
more light-sensitive 12-bit monochrome versions. It operates at
up to 1500 fps with 1920 ;
1080-pixel resolution from the
1920 ; 1440 native resolution
CMOS sensor. At reduced resolution, the camera can operate at 75,000
fps with a minimum global electronic shutter time of 2.7 µs (available
independent of the frame rate selected). Both C- and F-lens mounts are
provided with the large-format camera, which also is compatible with the
Canon ES/EF series lenses and available with PL and B4 lens mounts.
Memory sizes of 8, 16 and 32 GB are offered.

The PPS series analog laser
manufactured by Portable
Power Systems Inc. can operate in pulsed or continuous-wave mode. Depending upon
the unit, voltages range from
0 to 250 V and currents,
from 0 to 300 A. Rise times
of 15 µs and pulse widths of
25 µs are possible. Most units
house a universal input
power supply that accepts AC input voltages of 85 to 264 VAC. Higher-power units can work with an external power supply to reach significantly
higher power levels. The current can be controlled by a potentiometer on
the front panel or by accepting a 0 to 10-V analog signal via the rear
panel. The compliance voltage also can be adjusted via a potentiometer
on the front panel.

Princeton Instruments’ controller-less, cryogenically cooled CCD
cameras are designed for quantitative spectroscopy applications
that demand high sensitivity. The
first commercially available models are the PyLoN:100 and
PyLoN:400 dual-amplifier cameras, which use 1340 ; 100 and
1340 ; 400 sensors, respectively. In creating the new platform, the company redesigned
its Spec- 10 family of cameras to
remove the external controller,
thus increasing experimental
flexibility and improving the ultralow-noise electronics. Liquid
nitrogen cooling virtually eliminates dark current, and indium
metal seals enhance vacuum
longevity. Binning noise has
been reduced. The amplifiers and software-selectable gain permit operation in high-sensitivity mode for Raman or single-molecule spectroscopy,
and in high-capacity mode for fluorescence spectroscopy. The PyLoN:100
is suitable for rapid spectral acquisition and the PyLoN:400, for multiplexed spectroscopy.
