Product Family Description

Wavelength Range of 2 - 16μm
Durable Design for Demanding Applications
Superior Spherical Correction
Due to material supply chain disruptions with germanium, there may be increased lead times and price changes on our germanium products. For more information, please contact our customer service team.

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.
