Collimators
Collimators are devices used in space and astronautical engineering to control the direction and spread of radiation. They are used to create a well-defined beam of particles or waves by limiting the radiation emitted from a source to a specific direction. Collimators are commonly used in space telescopes to reduce the amount of stray light that enters the instrument and to improve the resolution of the images. They are also used in radiation therapy to target cancerous cells with high-energy particles while minimizing damage to healthy tissue. Collimators can be made of various materials, including lead, tungsten, and tantalum, depending on the type of radiation being controlled. They can be designed to have different shapes and sizes, depending on the application.
