Optical Windows are flat and optically transparent plates that helps to maximize transmission in a specified wavelength range and minimize reflection and absorption. These windows are typically used for safeguarding optical systems, electronic sensors, detectors, other sensitive optical components from being damaged by light. They are popularly used in imaging applications. They are also used as protective displays for variety of industrial or environmental applications. There are many different kinds of optic windows offered but reputed manufacturers for different purposes such as sapphire windows, Silicon Window, Germanium Window, Fused Silica Window, Magnesium Fluoride Window, and Calcium Fluoride Window etc. Different optical windows have different characteristic suitable to different purposes in the varied industries.
Sapphire is a crystal which synthetically grown in in large, somewhat cylindrical, boules. It is extremely hard and scratch resistant and hence sapphire windows are completely resistant to common scratches. It also effectively transmits throughout the visible and mid IR spectrum.Sapphire window is commonly used to protect more delicate optics sealed behind them such as commercial and military aircraft have a sapphire window protecting vision systems. Submarines use it to salt water abrasion. It is also used for many laser and LED applications. Germanium window are preferred for IR applications at a broad range of wavelengths and imaging applications. Fused silica windows are incredibly thermal shock resistant and carry good chemical resistance and optical transmission properties from ultra violet to infra-red. Magnesium Fluoride window is ideally used for UV radiation sources and receivers as well as in laser applications. As Magnesium fluoride is resistant to mechanical and thermal shock, laser damage and chemical etching. It is ideal for application where transparency is required across multiple wavelengths simultaneously, such as spectroscopy or fluorescence imaging of samples under vacuum and is also used for varied biological and military imaging applications. For the selection and/or evaluation of a suitable window material, one needs to consider different factors in mind, so as to properly assess the performance of an optical window. One should look for leading industry manufacturers to buy high quality optic windows for varied industrial applications.
