Laser Grade Plano-Convex (PCX) Lenses
• 6, 12, and 25 mm Diameter Lenses Also
Available Online
• 10-5 Surface Quality
• λ/10 Surface Accuracy
TECHSPEC® Laser Grade PCX Lenses are designed
for high energy Nd:YAG laser applications including
laser cutting, machining, and welding. The precision
fused silica substrate, featuring λ/10 surface accuracy
and 10-5 surface quality, ensures low scatter
and excellent transmitted wavefront performance.
TECHSPEC® Laser Grade PCX Lenses are available
uncoated or with a variety of high laser damage
threshold anti-reflection (AR) coating options. Coatings
are available at the most common Nd:YAG laser
wavelengths to ensure maximum laser throughput.

TECHNICAL NOTE
Laser Damage Threshold (LDT), also known as Laser Induced Damage
Threshold (LIDT), is one of the most important specifications to consider
when integrating an optical component into a laser application. The type
of damage induced to an optical component by a laser beam is dependent
on its wavelength, pulse length, polarization, repetition rate, and spatial
characteristics, among other factors. The failure mechanism of the optic
is related to either the substrate or coating. The table below lists the most
common variables that affect LIDT:
Edmund Optics® specifies many of its AR Coated TECHSPEC® optical lenses
with either a Laser Damage Threshold or a Typical Energy Density Limit.
Lenses designated with a Laser Damage Threshold have been designed,
and guaranteed, to withstand a certain level of laser fluence. Extreme care
is ensured throughout substrate preparation, cleaning processes, material
choices, coating design and deposition processes, and packaging to ensure
the lenses will not be damaged by the specified laser parameters. All
processes have been meticulously documented and lenses manufactured
with those processes have been rigorously tested by independent testing
houses via the ISO-21254 procedures and methods.
Lenses designated with a Typical Energy Density Limit are coated with an
anti-reflection (AR) coating that has been shown to withstand the specified
laser parameters. The lens substrates are manufactured according to
Edmund Optics’ world class manufacturing processes and standards, but
have not been specifically designed to withstand high energy lasers.
Whether a lens has a guaranteed laser damage threshold or a typical energy
density limit, the ultimate performance of the lens is highly dependent
upon the environment in which it is used. To maximize the lifetime and
performance of your lens, visit our website for application notes on proper
handling, cleaning, and storage of laser optics.
