Edmund Optics introduces TECHSPEC Lenses for Infrared
April 28, 2011, Barrington, N.J. - Edmund Optics introduces TECHSPEC Germanium Plano-Convex (PCX) Lenses. These lenses feature state-of-the-art, precision diamond turned surfaces, making them an ideal choice for a wide variety of infrared (IR) applications, including thermal imaging, IR spectroscopy and remote sensing.
TECHSPEC Lenses are manufactured from Germanium, which is a rugged, durable material with a broad transmission range and a high index of refraction. Germanium has a transmission range of 2 - 16 μm and is opaque in the visible part of the spectrum, making it ideal for IR laser applications. The material is inert to air, water, alkalis and all acids, with the exception of nitric acid. With a density of 5.33 g/cm3 and a Knoop Hardness of 780, nearly twice that of Magnesium Fluoride, Germanium is an ideal material for making rugged, durable IR optics.
TECHSPEC Lenses are available in 25 mm and 50 mm diameters. These uncoated lenses feature a positive focal length, ranging from 25 mm to 250 mm, and have one flat and one convex surface. TECHSPEC Germanium Plano-Convex (PCX) Lenses are ideal for collimation and focusing applications using monochromatic illumination in a wide variety of defense, security and thermal imaging applications.
