摘要:
The finder optical system has a reflex mirror, a focal plane plate, a prism, an eyepiece, and a dust-proofing multilayer. The reflex mirror is disposed on an optical path of a photographing optical system. The focal plane plate is disposed at a position on which an image is formed by a light which passes through the photographing optical system and which is reflected by the reflex mirror. The light-input surface of the prism races a light-output surface of the focal plane plate. The eyepiece faces a light-output surface of the prism. The dust-proofing multilayer, which is provided on a surface of the focal plane plate, has a water-repellent or water- and oil-repellent layer and an anti-static layer.
摘要:
A stage apparatus includes a stationary support member, a movable stage plate supported by the stationary support member to be movable in a plane relative to the stationary support member, at least one magnetic force generator which is provided integral with the stationary support member, and at least one coil which is mounted on the movable stage plate and receives a magnetic force generated by the magnetic force generator to produce a driving force for driving the movable stage plate in the plane. At least one hole in which the coil is fixedly fitted is formed on the movable stage plate.
