Window is a piece of glass with plane parallel surfaces used to admit light into an optical system and to exclude dirt and moisture.
There can be extreme differences of temperature, pressure, humidity and other parameters on either side of the window. When selecting windows the optical, mechanical and thermal properties must be considered according to the intended use: It should be of 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.
Windows may also be used as coating substrates for use in a wide range of applications. TEMTO provides varieties of single layer or multiplayer anti-reflecting coating on optical windows. Please refer to Coatings chapter for more information.
