Design of 90° off-axis paraboloid (OAP) mirrorOff-Axis Parabolic (OAP) mirrors are part of the primary paraboloid. Off-axis means that the optical axes of the two are parallel but not coincidence. Th...

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 ...
