ARRANGEMENT FOR MEASURING LASER RADIATION'S PARAMETERS

摘要

FIELD: measuring technique. ^ SUBSTANCE: in the arrangement a reflective element is located in a body fulfilled in the shape of a tube in which a reflective screen is installed from the outside of the exit of radiation. The screen is fulfilled in the form of a hollow cone whose top is directed towards the reflective element. Between the screen and the reflective element protective screens fulfilled in the shape of diaphragms are installed on the surface of the body perpendicularly to it. ^ EFFECT: increases accuracy of measuring. ^ 2 cl, 4 dwg
