In a machine vision system, the lens acts as the eyes of the machine. Its primary function is to focus the image of the target object onto the photosensitive device of the image sensor (camera). All i...

Understand the imaging principle of aspherical lens, the characteristics and advantages compared with spherical lens.

Optical components are widely and critically used in machine vision. Machine vision, as an important branch of artificial intelligence, simulates the human visual system, using computers, cameras and ...

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...
