WINDOWS AND OPTICAL FLATS
Optical windows are used to create a physical barrier between two different environments.
This prevents unwanted mixing, isolating liquids from the air and maintaining system’s vacuum state.
Optical windows are used in many optical systems to protect optical components from cases like back-splatter and out-gassing.
While optical windows can be manufactured in various shapes, they are typically produced in round or rectangular shapes.
Moreover, optical windows are constructed with two flat (PLANO) polished surfaces that possess optical characteristics.3L-Systems provides prototype and mass-produced optical windows applicable to ultraviolet, visible,and infrared wavelength ranges.
