Circular Windows – Standard Plane-Parallel Optical Protection Windows
Detailed Description:
Circular Windows are the most common type of plane-parallel optical windows, featuring a circular shape and high parallelism to minimize wavefront distortion. They are used to protect optical components, detectors, and lasers from environmental factors while transmitting light with minimal loss and aberration. Our circular windows are available in a wide range of materials and coatings to suit various applications.
