Title:
LASER REFLECTING MIRROR
Document Type and Number:
Japanese Patent JPH01303404
Kind Code:
A
Abstract:
PURPOSE:To eliminate the stains of a reflecting mirror without damaging the surface at a low cost by forming a thin film consisting of molybdenum on a reflecting mirror base plate consisting of copper or alloy essentially consisting of copper. CONSTITUTION:The thin film 7 consisting of the molybdenum is formed on the reflecting mirror base plate 1 consisting of the copper or the alloy essentially consisting of the copper. The surface hardness is thereby increased in the same manner as with a laser reflecting mirror consisting of the molybdenum as a base plate. Even if, therefore, sputters and the scorches of mists, etc., are deposited on the reflecting mirror during the use thereof, such stains can be wiped away by a solvent such as trichloroethylene or alcohol to clean the surface. Removal of the stains such as sputters with a nylon brush, etc., is possible as well. The inexpensive cleaning of the laser reflecting mirror is attained in this way and the surface flawing is obviated even if the surface stains are removed.
