The role of collimator

Do you know what is the function of the collimator? Today, the editor will explain to you the function of the collimator.
The collimator is a component of the radiation head of a medical accelerator. The component that produces the contoured radiation field of a certain shape is called the collimation system, and the component that produces the contoured radiation field of the regular shape is called the regular field collimation system. The regular field refers to a square, rectangular or circular radiation field with a variable size.
The function of the collimator is to make the coupling of the light into the required device with the maximum efficiency or as easy as receiving the optical signal with the maximum efficiency. So it has an important parameter: insertion loss, the current process technology can reach below 0.15dB.
The collimator is an optical component used for input and output of optical fiber communication optical devices, and its structure is very simple-the divergent light from the optical fiber is turned into parallel light (Gaussian beam) through a front similar convex lens. Its function is to make the coupling of light into the required device with maximum efficiency or as easy as receiving the optical signal with maximum efficiency. So it has an important parameter: insertion loss, the process technology can reach below 0.15dB.
In addition to the use of primary and secondary collimators for the collimation of electron radiation, an electron beam limiter (Aplicator) is equipped under the radiation head. Its main function is to limit the range of electron radiation in order to protect normal tissues outside the target area. And to protect vital organs from exposure.
