Film photomasks play a vital role in modern optical production, semiconductor patterning, PCB development, and various micro-fabrication processes. They serve as high-precision pattern carriers, enabling accurate light-based imaging or etching on different substrates. In this article, I will explain how a Film Photomask works, why it is important, and what technical parameters make our solutions from Ningbo Zhixing Optical Technology Co., Ltd. reliable. Clear structure, easy-to-read language, and professional depth are maintained throughout.

In the fast-evolving field of optical metrology, CGH Cylinder Nulls have emerged as indispensable tools for precision testing and calibration of cylindrical and aspheric surfaces. By replacing complex mechanical setups with computer-generated holography (CGH), these null correctors enable ultra-precise surface verification in high-end optical systems such as telescopes, camera lenses, and semiconductor inspection instruments. This article explores how, why, and what makes CGH Cylinder Nulls vital for industries seeking sub-micron accuracy and cost-effective testing solutions, while also highlighting the professional excellence of Ningbo Zhixing Optical Technology Co., Ltd., a leading manufacturer in this field.

CGH Null Correctors (Computer-Generated Hologram Null Correctors) are advanced optical testing devices used to measure and correct aberrations in precision optical systems, such as aspheric and freeform lenses or mirrors.

Film Photomask is a master plate used for integrated circuit wafer manufacturing, carrying relevant information of the integrated circuit design layout. In the wafer manufacturing process, the pattern on the Film Photomask is transferred to the exposed substrate material through a series of processes such as photoresist coating, exposure, and development to achieve pattern transfer.

A Photomask, also known as a light mask, photomask, or photolithography mask, is a master pattern used in the photolithography process in microelectronics manufacturing. The following is a detailed introduction to it:

When responding to the tariff adjustment by the United States, the optical industry needs to adopt multi-dimensional strategic measures to balance cost pressure, maintain market share and promote industrial upgrading. The following is the specific strategy analysis:
