Description

technical field

[0001] The invention relates to the technical field of optical measurement, in particular to an on-line measuring device for gamma radiation optical glass transmittance and an on-line measurement method for gamma radiation optical glass transmittance. Background technique

[0002] Optical glass is the basic material of the main optical components in the space optical system, and its transmittance is necessarily related to the system performance. The space radiation environment can affect the absorption properties of optical glass, thereby changing its transmittance. Different materials of optical glass are affected by space radiation in different degrees. For this reason, it is necessary to conduct gamma-ray irradiation experiments (simulating the space irradiation environment) on optical glass during the development of space optical systems to evaluate and screen optical glass for space optical systems.
