White light interferometer, as a kind of ultra-fine surface profile measuring instrument, has shown its great strength in many fields by virtue of its high precision and wide applicability. The following are the main application areas of white light interferometer:

Semiconductor Manufacturing and Testing:

During semiconductor manufacturing, the thickness and flatness of the film as well as the microstructure of the wafer surface are critical. White light interferometry can accurately measure these parameters to ensure the performance and quality of semiconductor devices. It can also be used to detect defects in semiconductor devices, such as cracks and bubbles, to guide the repair and optimization of the production process.
 

Optical component manufacturing and testing:

For optical elements such as lenses and prisms, their surface quality and morphology directly affect the propagation and focusing effect of light. White light interferometer can measure the surface profile and roughness of these elements with high precision, providing key data for the design and optimization of optical systems. In addition, it can also be used to detect the coating quality of optical elements to ensure the stability and reliability of optical performance.
 

Machining and quality testing:

In the field of machining, white light interferometer can be used to measure the precision, surface roughness and small deformation of machine tools. Through real-time monitoring and data analysis, errors in the machining process can be found and corrected in time to improve the machining accuracy and consistency of products. At the same time, it can also be used to detect surface defects and wear of mechanical parts, providing strong support for equipment maintenance and repair.
 

Life Science Research:

In the field of life sciences, the application of white light interferometry is also becoming more and more widespread. It can be used to measure the morphology and structure of microscopic organisms such as cells and bacteria, providing important morphological data for biological research. In addition, it can be used to study the interaction and deformation process of biomolecules, revealing the microscopic mechanism of life phenomena.
  

Materials Science Research: 

  
For the research and development of new materials, white light interferometry can provide key information such as material surface topography, roughness, and film thickness. This information helps researchers to understand the performance characteristics and application potential of materials, and promotes the progress and development of materials science.
 

 With its high precision and wide range of applications, white light interferometer plays an important role in many fields such as semiconductor manufacturing, optical component manufacturing, mechanical processing, life science research and material science research. With the continuous development of science and technology, the application areas of white light interferometer will be further expanded to provide strong support for the research and development of more fields.
