- Relay Optic
- ˈɹiˌɫeɪ ˈɑptɪk
Relay optics are optical systems used to transfer an image or a light beam from one position to another without changing the optical properties of the original image. It typically consists of one or more lenses or mirrors that are carefully arranged to create such a "relay" system.
Relay optics are commonly used in a variety of applications, including microscopy, telescopes, laser systems, and imaging systems. For example, in microscopy, relay optics can be used to transfer the image of a specimen from the objective lens to the eyepiece or camera. In laser systems, relay optics can be used to transfer a laser beam from one component to another without changing the beam's properties.
The design of relay optics depends on the specific application and the desired properties of the image or light beam being transferred. Factors such as the size, shape, and wavelength of the light, as well as the distance and angle between the original and final positions, must be carefully considered in order to achieve optimal performance.
