Although the mechanical power of components is changed, the optical system products are usually built between 100 mm and 300 mm in diameter. It makes a very small, yet very important part. These parts are different in price and are based on size and usage.
For such a small thing used to build machinery, the price is very great, but when they are no other way around electronics it is so important they are made silicon for electronics applications but other materials are also functional. These small pieces were used in various electronics. Computers are clear but others include cell phones as well as any digital devices.
