WebFor example, the often used BK7 glass is a crown glass (see below) of that type. Borosilicate glasses are chemically quite resistant, if the boron content is not too high. Compared with fused silica, they have a lower (although still relatively high) melting temperature, which makes them simpler and therefore cheaper to process. WebThe Importance of Using the Correct Material. Since infrared light is comprised of longer wavelengths than visible light, the two regions behave differently when propagating through the same optical medium. Some materials can be used for either IR or visible applications, most notably fused silica, BK7 and sapphire; however, the performance of ...
