The Chinese Space Station Telescope (CSST), as a type of optical telescope, can capture the spectrum from near-ultraviolet to visible light. By combining a primary mirror with a large diameter and lon...

With the development of science and technology, the means of optical processing continue to evolve. The processing methods of optical surface have been developed from traditional methods of low effici...

As the demand for imaging quality continues to rise in the market, high-precision optical aspheric lenses are increasingly being used in optical instruments, space laser communication, aerospace, and ...

Aspheric design offers greater degrees of freedom, allowing for better aberration correction. The application of aspheric surfaces adds many degrees of freedom to off-axis optical systems. However, co...

Optical components are devices used to control, regulate, convert and manipulate optical signals, and they play an important role in optical systems and optical instruments. According to the different...

Optical freeform surfaces can achieve functionalities in optical systems that are difficult to realize with traditional spherical or aspheric surfaces alone. They require fewer components, making the ...

Taking clear pictures despite poor lighting conditions, taking snapshots without blurring, recognizing traffic signs and road markings, or identifying dangerous situations with a specific system - all...

A cylindrical mirror has curvature in one dimension and is used to focus a light source into a one-dimensional shape. In other words, changing the way the light source in an optical system and convert...
