Product introduction:

Borosilicate glass 3.3 is a type of glass that has become increasingly popular in recent years, due to its excellent thermal and chemical resistance properties. It is composed mainly of silica, boric oxide, aluminum oxide, sodium oxide, and other oxides. This specific combination makes it ideal for use in optical lenses as well as various types of laboratory equipment. Borosilicate 3.3 glass can be used as optical lens for cameras and other equipment.At the same time, its wear resistance is also very prominent.

Borosilicate Glass Optical Lenses are used for a variety of applications such as microscopy and telescopes. The combination of the borosilicate glass material with the precision-made optics allows for superior performance when compared to standard plastic or acrylic lenses. Additionally, Borosilicate Glass Optical Lenses provide increased clarity and color fidelity which helps reduce eye fatigue during extended viewing sessions. 

The composition of Borosilicate Glass 3.3 makes it particularly suitable for high temperature use without compromising on strength or durability; this property can be beneficial when creating optical lenses which require higher temperatures during production processes than what traditional glasses can handle without cracking or melting under pressure.

Advantages

High borosilicate 3.3 glass is high-temperature resistant glass, heat-resistant glass and temperature difference resistant glass. The linear expansion coefficient is 3.3 ± 0.1 × 10-6 / K, is a glass with sodium oxide (Na2O), boron oxide (b2o2) and silicon dioxide (SiO2) as the basic components. The content of boron and silicon in the glass composition is relatively high, namely, boron: 12.5 ~ 13.5%, silicon: 78 ~ 80%.

The expansion coefficient will affect the stability of glass. The expansion coefficient of borosilicate 3.3 heat-resistant glass is 0.4 times that of ordinary glass. Therefore, at high temperature, borosilicate 3.3 heat-resistant glass still maintains excellent stability and will not crack or break.

Note:

Borosilicate Glass 3:3 offers many advantages regarding its usage when making complex optical lenses such as microscopes or telescope components; not only does it have excellent properties against heat distortion but also provides exceptional clarity & colour fidelity necessary when viewing objects at either microscopic level or great distances away respectively - offering users much better visual experiences than many other materials out there today regardless if they’re using them recreationally through hobbyist activities like astronomy/birdwatching etc., professionally through medical research etc.
