Optical component monitoring method, e.g. for lenses used with high energy lasers, whereby a representative length is measured that arises due to a temperature change and this is then related to a change in optical properties

摘要

Method for monitoring optical components in order to detect a change in their optical properties, whereby a length change in the optical component (1) is measured and from it a temperature change calculated, which would be deemed to cause a particular change in the component optical properties. The invention also relates to a corresponding device for carrying out the inventive method.
