• Diffraction Limited Performance
• Variety of Coating Options
• Full Prescription Data Available
Our TECHSPEC® Germanium IR Aspheric Lenses
provide diffraction limited focusing performance
over a broad spectral range in the Mid- and Long
Wave infrared regions. Ideal for monochromatic light
sources, such as quantum cascade lasers, these lenses
offer a high performance alternative to standard
plano-convex lenses. See our website for curve for focusing
performance comparison between PCX lenses
and our TECHSPEC® aspheres at various f/# ratios.

TECHSPEC® Germanium Meniscus Lenses are designed
for demanding infrared applications including infrared
imaging or surveillance, remote sensing, or infrared spectroscopy.
TECHSPEC® Germanium Meniscus Lenses offer
superior spherical correction and smaller spot sizes
than comparable focal length TECHSPEC® Germanium
PCX Lenses. These meniscus lenses are offered uncoated
or anti-reflection coated for increased performance in
the designated coating wavelength range.
