Safety filter for an ophthalmic therapeutic and/or diagnostic instrument |
摘要 |
The invention is directed to a safety filter for an ophthalmic therapeutic and/or diagnostic unit into which a laser beam is coupled for therapeutic purposes. The safety filter is optically dimensioned in such a way that no change in the focal intercept results when the filter is swung into the viewing beam path. The filter largely absorbs the particular laser wavelength.
