Product Description
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 Shape of High Precision Optical Windows
Oplens can use laser machining capabilities to manufacture high precision optical windows in a variety of shapes and sizes to meet your specific needs.
The following shapes of optical windows are available:
1. Square
2. Quarter Wave Windows
3. Rectangular Windows
4. Elliptical Windows
