Title:
FORMING METHOD FOR HIGH-ACCURACY MIRROR
Document Type and Number:
Japanese Patent JPH025001
Kind Code:
A
Abstract:
PURPOSE:To mass-produce the high-accuracy mirror which has an excellently flat and specular surface at low cost by flattening photosensitive resin with which the surface of the substrate is coated by a flattening member, curing the surface, and vapor-depositing a high-reflection-factor member. CONSTITUTION:The surface of a metal member 7 which has flatness is coated with the photosensitive resin 8 and a transparent master member 9 is brought into contact with its top part as the flattening member. While the master member 9 is in contact, a resin curing means exposes the photosensitive resin 8 to light matching its absorption wavelength lambda to fix and stabilize the resin and the master member 9 is separated from the metallic member 7, thereby making the surface of the photosensitive resin 8 specular. Lastly, Al 10, etc., as the high-reflection-factor member having a high reflection factor is vapor- deposited by usual vacuum-depositing technique on the surface of the photosensitive which is held specular. Consequently, the high-accuracy mirror which has the excellently flat and specular surface is mass-produced at low cost.
