Mid-Wave and Long-Wave Infrared (IR) Aspheric Lenses

Mid-Wave and Long-Wave Infrared (IR) Aspheric Lenses
  • Wavelength Range of 1 - 14µm
  • Variety of Coating Options
  • Mounted and Unmounted Versions

Our infrared aspheric lenses are ideal for a variety of mid-wave and long-wave infrared applications. The low-cost, molded design offers several key benefits over Germanium substrate aspheres. With a dn/dT and CTE significantly less than that of Germanium, our lenses feature a smaller change in focal length as a function of temperature change. And, with a higher operating temperature than Germanium (which suffers 20 – 30% transmission loss at 100°C), our lenses can be used in applications that were not previously possible with Germanium.

The Mid-Wave and Long-Wave Infrared (IR) Aspheric Lenses are available with a variety of coating options. For custom requirements, including custom coatings, custom designs, or adding diffractive features to the aspheric surface, please contact our Sales Department.
