- Коллиматор
- Optical device consisting of two lenses separated by the sum of their focal length. it is used to provide desired beam diameter to meet specific beam delivery requirements.
- An optical instrument consisting of a well-corrected objective lens with an illuminated slit or reticle at its focal plane. collimators are used in lens testing to determine focal lengths, and in other metrological applications where a distant object at a known location is required.
- Device for restricting the size, shape, and direction of the irradiating beam, thereby limiting beam spread and its consequences.
- Устройство для ограничения размера, формы и направления облучающего луча, тем самым ограничивая распространение луча и его последствия.
- In radiographic testing, device for restricting the size, shape and direction of the irradiating beam, thereby limiting beam spread and its consequences.
