Prism&C Lens Polishing


Alpha Optik optical windows are commonly used to isolate two atmospheric regions of an optical system while permitting light to pass. The quality of the window can be critical. It should be with high purity and polish in order not to affect the optical system. When large pressure differences are anticipated across the window extra thickness will be required to hold the flatness and parallelism specifications.
