external attenuation using a dual plate attenuator.
Attenuator modules, as depicted in figure 3, left, are either
controlled manually or motorized with feedback diode and are
increasingly used as a convenient add-on in PLD labs.
Dual plate attenuators work via two…

transits of the attenuator before returning to the source and the
perturbation effect disappears quickly.…

…Face Plate
(LDFP)
The Low Distortion Face Plate provides a protective window for the
camera array that also acts as a background attenuator with 0.04% to
0.05% typical. The LDFP is made of laser grade filter glass that
minimizes interference fringes--refer to "Fringes" (p.…

the test slide is inserted into the beam and then examined for damage.
These test slides are coated with the same absorbing coating as the
pyroelectric sensors. If coating damage is visible, then attenuation is
required before measuring the beam.

blooming effects, whereas CMOS sensors are not. Attenuation will
likely be needed when use camera-based systems with higher
power lasers, and careful attention must be made to the quality of…
