A flat concave lens is an optical element with special optical properties. What are the applications of flat concave lenses?

broaden sb.'s outlook

In special application scenarios such as military observation and security monitoring, the divergent effect of flat concave lenses can disperse light and help observers see a broader field of view.

As a beam expander

In the fields of laser technology, optical instruments, and optical communication, flat concave lenses can diffuse the incident parallel beam, making it wider and meeting specific application requirements.

As a converging lens

In the fields of optical imaging, photography, and microscopy, flat concave lenses can converge the incident divergent beam of light to a single point, achieving light focusing and obtaining clearer images during imaging or observation.

Making optical components

The special optical properties of flat concave lenses make them an ideal choice for producing optical components such as reflectors, beam splitters, and filters. These components play a precise control and adjustment role in optical systems to achieve specific optical functions.
