TECHSPEC® Zinc Selenide (ZnSe) Aspheric Lenses
are designed to provide diffraction-limited focusing
performance for 10,6 μm CO2 lasers. Manufactured
from II-VI Infrared ZnSe material featuring < 0,0005
cm-1 bulk absorption at 10,6 μm, these lenses are
available uncoated or with a broadband anti-reflection
coating providing superior transmission from
8 - 12 μm. 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 10,6 μm, 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 < 0,0005 cm-1 bulk
absorption at 10,6 μm and are available uncoated or
with a variety of broadband anti-reflection coating
options. The 8 - 12 μm coating is ideal for use with
CO₂ lasers and thermal camera applications, whereas
the dual band 3 - 12 μm coating is ideal for hyperspectral
applications. TECHSPEC® Zinc Selenide PCX
Lenses feature an irregularity of < λ/20 at 10,6 μm,
40-20 surface quality, and < 50Å surface roughness.
Three diameter options are available, with effective
focal lengths ranging from 12,7 mm to 200 mm.
