subject: Optical Filter Glass: Crucial Component In Transmitting & Blocking [print this page] Glass, one of the most useful materials in the world, is made from silica sand, soda ash and limestone. In our day to day life, there are endless uses of glass. For instance, you can preserve the food in glass jar, use glasses to drink water, use glass in windows, use in motor vehicles, wear eyeglasses and many more. In short, we cannot imagine our daily life without glass. When we talk about glass, generally a transparent, shiny substance that breaks rather easily suddenly comes in our mind. But today, glass is available in various forms and Optical glass is one of them. Optical glasses are nothing but the glasses used in expensive and sensitive products like eyeglasses, camera lenses, microscopes, telescopes, and many other instruments that used in factories and laboratories. Optical glass suppliers can provide superior quality and almost flawless optical glasses by using pure raw materials. To manufacture optical glasses lots of care is require which makes it pricey as compared to other kinds of glass available today.
Optical filter glasses has become crucial components in transmitting and blocking some particular spectral ranges, and usually used in many application areas like regulation, industrial measurement, control technology, research and development, analytical measurement methods in production, environmental protection, medicine and military. Optical filter glasses are used for many applications like medical, imaging, inspection and industrial applications. And today, they have become an industrial standard and are essentially needed for a variety of technical applications and for professional research.
Optical glass filters are created by the processing of unrefined raw optical filter glass material, rolled sheets or block raw materials. They are recognized for its selective absorption in the visible wavelength range. If their filter affects deceit within the visible light spectrum, the optical color filters appear to be colored. In order to build up a variety of colored glass filters, some excessive filter properties, in the largest possible spectral area with different concentrations and many different base glasses have been developed.
optical glass filters are formed and supplied in various thicknesses ranging from 1 mm to 400 mm depending on raw glass size. And, by combining different filters together we can obtain extra filter effects. The polished and cut filters can be tough for particular applications. Optical glass filter can be used as substrates for thin film coating to produce interference filters. Optical glass filter can be customizes according to the customer's specifications, according to ISO 10110 and according to MIL specifications.
