With the progress of science and technology and the continuous expansion of optical applications, the application prospect of calibration board is increasingly broad. This paper will discuss the application prospect of calibration board in optical industry in detail from the basic concept, application field, market demand and future development trend of calibration board.

As a standard instrument, wire gauge plays an indispensable role in the field of precision measurement. It is famous for high precision, high reliability and high stability, and is widely used in many fields such as mechanical manufacturing, optical instruments, electronic technology and so on. Especially in the optical industry, the application prospect of wire scale is very broad.

Mask plate, also known as photomask or photomask plate, is a graphics transfer master in the process of microelectronics manufacturing, and is an important key material in the manufacturing process of flat panel display, semiconductor, touch control, circuit board and other industries. As the benchmark and blueprint of lithographic reproduction, mask plate has a broad application prospect in the optical industry, and its technical development and market demand are showing a positive growth trend.

Photomask (Photomask), also known as photomask, photomask, lithography mask, etc., is a graphic master used in the lithography process in microelectronics manufacturing. The mask version achieves mass production by transferring the designer's circuit pattern to the substrate or wafer in the downstream industry by means of exposure. It plays a vital role in the manufacturing process of flat panel display, semiconductor, touch control, circuit board and other industries.
