The lack of symmetry in the free form allows for more complex control over the path of light rays. This allows free-form surfaces to correct aberrations more efficiently than conventional optics, espe...

The correct use of aspheric surfaces is crucial, including decisions on which surface to make aspheric and whether to use conic sections or higher order aspheric. Conic sections include parabolic, hyp...

Optical specifications are utilized in the design and production of a component or system to enable the component or system to accurately meet specific performance requirements. Optical specifications...

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...
