Optical Grade Sapphire Large Lens with C-axis Orientation 90% Clear Aperture Precision Surfaces
Sapphire Optical Windows are flat, optically transparent plates that are typically designed to maximize transmission in a specified wavelength range, while minimizing reflection and absorption. They are often used to protect optical systems and electronic sensors from an outside environment. Because windows introduce no optical power into a system, windows should be selected based on the material transmission properties, optical surface specifications, and the mechanical properties that match your application.
The following shapes of optical windows are available:
1.Square
2.Circle
3.Quarter Wave Windows
4.Rectangular Windows
5.Elliptical Windows
We supply a range of optical windows in a selection of materials to meet all scientific instrument applications from UV-Visible and IR wavelengths.
