Patent number: 7841744Abstract: The illumination apparatus comprises a light source unit which has a LED for emitting illumination light, and a condenser lens for collecting the illumination light, and a main body of the illuminator of the apparatus which holds the light source unit and guides the illumination light. The light source unit comprises a heat dissipation plate which holds LED, and emits the heat emitted from LED 11; and a lens frame which holds the collector lens and the heat dissipation plate so that the relative position of LED to the collector lens may be changed. The main body of the illuminator has a connection hole for connecting communicatively the inside of the main body of the apparatus to the outside, and holds the light source unit by inserting the lens frame into the connected hole.Type: GrantFiled: June 20, 2008Date of Patent: November 30, 2010Assignee: Olympus CorporationInventor: Masahito Tonooka

Publication number: 20060114555Abstract: A lens barrel movable portion to which an eyepiece lens is attached is swiveled with respect to a main body. A first reflecting member which reflects a light beam from a microscope main body swivels in conjunction with swiveling of the lens barrel movable portion. An angle of swiveling is ½ of a swiveling angle of the lens barrel movable portion. A direction of swiveling is the same as a rotating direction of the lens barrel movable portion. As second reflecting member reflects a light beam reflected by the first reflecting member toward the eyepiece lens.Type: ApplicationFiled: October 12, 2005Publication date: June 1, 2006Applicant: OLYMPUS CORPORATIONInventor: Masahito Tonooka
