Infrared Aspheric Lenses
Category
Infrared Optical Elements
- Substrate:Silicon, germanium, zinc selenide, zinc sulfide, calciumfluoride.Chalcogenide glass and other infrared materials
Product Description
Aspheric lens has better curvature radius and can maintain cood aberration correctionto obtain the required performance. The application of aspheric lens brings excellentsharpness and higher resolution, At the same time, miniaturization design of lens becomespossible. Spherical aberration often limits the diffraction limit design of spherical lens.Aspheric lenses are designed to minimize spherical aberration, providing a reliable singleoptical element solution for many applications.
