TECHSPEC® Zinc Selenide (ZnSe) Aspheric Lenses
are designed to provide diffraction-limited focusing
performance for 10.6μm CO2 lasers. Manufactured
from II-VI Infrared ZnSe material featuring <0.0005
cm-1 bulk absorption at 10.6μm, these lenses are
available uncoated or with a broadband anti-reflection
coating providing superior transmission from
8 - 12μm. The precision designs are ideal for
integration into laser systems, thermal imaging
assemblies, and FTIR devices. TECHSPEC® Zinc
Selenide Aspheric Lenses feature an irregularity of
<λ/20 at 10.6μm, 40-20 surface quality, and <50Å
surface roughness.

TECHSPEC® Zinc Selenide (ZnSe) Plano Convex
(PCX) Lenses are designed for focusing or collimation
applications in the mid-wave and longwave infrared
spectrum. Manufactured by II-VI, these lenses feature
Infrared ZnSe material with <0.0005cm-1 bulk absorption
at 10.6μm and are available uncoated or with a
variety of broadband anti-reflection coating options.
The 8 - 12μm coating is ideal for use with CO₂ lasers
and thermal camera applications, whereas the dual
band 3 - 12μm coating is ideal for hyperspectral applications.
TECHSPEC® Zinc Selenide PCX Lenses feature
an irregularity of <λ/20 at 10.6μm, 40-20 surface
quality, and <50Å surface roughness. Three diameter
options are available, with effective focal lengths ranging
from 12.7mm to 200mm.
