What are optical instruments made of?

Many people are struggling with this issue. Some materials say that optical instruments are made of quartz glass, and some people say that optical instruments are made of quartz crystal. In fact, there are many different types of optical instruments, and different materials will be used to make them according to different needs of optical instruments.

Quartz glass tube

The purity of quartz in quartz glass is very high, that is, the purity of silica is high. It is almost always used in the lenses of general optical instruments, such as camera lenses, high-end glasses, etc. The transmittance is very high. Many of today's glasses are made of synthetic resin, but high-end glasses are still made of quartz glass. Such products not only have high permeability, but also have high hardness. Generally, they will not break when dropped on the ground.

The composition of quartz crystal and the composition of quartz glass are the same, but the difference between the two is the purity. The purity of quartz crystal is much higher than that of quartz glass, and the internal structure of the crystal is crystalline. The physical and chemical properties are very good. Acts on polarization and oscillation functions.

In summary, it can be known that both quartz glass and quartz crystal can be used to make optical instruments, but different types of optical instruments use different materials. It can also be known from the price that optical instruments made of quartz glass are more expensive than quartz crystals. Cheap.

These are all articles about whether optical instruments are made of quartz glass or quartz crystal.
