Glass substrates are produced and coated by a highly skilled level of people who ensure that it has the right degree of stain on it, is sensitive to temperature and the right gradient index. Glass substrates are typically fixed inside a metal housing or a ferrule to add durability. Every thin film design of the glass substrate is fixed with beam spluttering and ECI band stop to ensure that the coating on the glass substrate remains sturdy and optimal for continued use.
There are a variety of glass substrates with different type of conductive coating that you will find in the market today. Here are a few of them:
AR Coatings: These are narrow, built with a dual band but broad by design. They are suitable for ultra thin wafers and temperature sensitive material that lies in a range of 200 nm to 2500 nm.
Custom optical filters: Ranging between 240 nm to 2600 nm, these optical filters include long and short wave pass band pass and Dichroic density filters to provide optimum results.
Metal mirror coatings: The designs of these glass substrates include gold, silver and aluminium back surface reflectors for optimum results.
Dielectric mirror coatings: These are reflective and broad band which enhances the durability of the glass substrate.
Laser mirror coatings: these are highly reflective in nature with a low laser loss feature.
Transparent conductive coatings: These are built with a hybrid and transparent conductive coating and is mostly brought into use in military, medical and security applications. They also provide stability to the environment and can also be designed with a custom design.
Beam splitter coatings: These are designed to separate the incoming stream of light and mainly consists of reflected and transmitted beams. These coatings are mainly designed to be used for longer durations.
