Description

  The present invention relates to a camera adapter for mounting a camera on a lens barrel of a microscope and taking a specimen image via an eyepiece.

  There has been proposed a camera adapter that includes an insertion portion that is inserted into an eyepiece lens attachment port of a microscope and a connection portion that is connected to a camera lens (see Utility Model Registration No. 3068547). This camera adapter requires a screw part (generally a filter frame) for attaching the adapter to the camera side, and cannot be applied to a camera without a filter screw. Moreover, since the lens is built in the adapter, it becomes expensive.

  A camera adapter is also commercially available in which an adapter is attached to the outer periphery of an eyepiece sleeve for an astronomical telescope and the camera is fixed with screws. The camera adapter is fixed while the adapter fixing portion (hollow cylindrical shape) is placed on the outer periphery of the eyepiece sleeve and pressed from the side with a screw. For this reason, the optical axis of a camera will shift | deviate by tightening of the screw at the time of fixing. In addition, since the camera adapter is directly connected to the adapter fixing part, the adapter must be attached and detached each time observation and photographing are repeated. This is troublesome because the optical axis of the camera must be aligned.

  In addition, an adapter has been proposed in which a camera adapter body is fixed to a first eyepiece sleeve of a binocular tube portion of a microscope, and a specimen image is taken from the second eyepiece sleeve via an eyepiece lens (Patent Publication No. 2002). -350740). Since this adapter is connected to the eyepiece sleeve in a fitted state, the fixed position of the camera can be easily reproduced as compared with the above-mentioned astronomical telescope adapter, but the position of the optical axis must be adjusted. Moreover, this adapter can be connected only to a binocular microscope, and lacks versatility.

  An object of the present invention is to provide a camera adapter for a microscope that is inexpensive and versatile, and that allows the camera to be easily attached to and detached from the microscope.

  In order to solve the above-mentioned problems, the present invention has taken the following measures.

  The present invention is a camera adapter for a microscope for mounting a camera that takes a specimen image from a lens barrel portion of a microscope through an eyepiece to the microscope, and an adapter fixing for fixing a camera adapter body to the lens barrel portion.
