Device for taking stereoscopic photograph in a stereoscopic microscope

Claim 2

Device for taking stereoscopic photograph in a stereoscopic microscope having two optical axes in each of which an objective lens and an ocular are optically arranged for the microscopic observation of an object therethrough, said two optical axes forming a parallax angle therebetween so that stereoscopic observation is achieved when the object is viewed simultaneously through said two optical axes, wherein the improvement comprises a camera body having an optical axis located in symmetry with respect to said two optical axes and adapted for having a film loaded therein, and an optical path switching means, at least a portion of said optical path switching means being rotatable about sAid optical axis of said camera body between a first position at which a portion of the light from the object in one of said two optical axes is reflected twice so as to be directed to said optical axis of said camera body so as to form an image of the object on said film and a second position at which a portion of the light from the object in the other of said two optical axes is switched to be directed to said optical axis of said camera body so as to form an image of the object on said film, thereby permitting a set of stereoscopic photographs of the object to be obtained by successively taking photographs at said first and second positions of said optical path switching means, respectively, while permitting the stereoscopic observation of the object.

Claim 3

Device according to claim 1, wherein said optical axis of said camera body is offset from the plane in which said two optical axes of the microscope are located, thereby permitting the observation through said ocular in each of said two optical axes to be facilitated without causing the interference between said oculars and said camera body.

Claim 4

Device according to claim 2, wherein said optical axis of said camera body is inclined at an angle with respect to the plane including said two optical axes so that the rotation of the image formed on said film about the center thereof which is caused by the parallax angle between said two optical axes and the deviation of the light in each of said two optical axes out of the plane including said two optical axes by means of said optical path switching means is compensated for.

Claim 5

Device according to claim 1, wherein said optical path switching means comprises a light reflecting means and a semitransparent light reflecting means integral with said optical path switching means, said light reflecting means being rotatable about the optical axis of said camera body while said semitransparent light reflecting means is brought into either of the two optical axes of the microscope when said optical path switching means is rotated to either of said first and second positions.

Claim 6

Device according to claim 1, wherein said optical path switching means comprises a light reflecting means rotatable about said optical axis of said camera body and a semitransparent light reflecting means located stationarily in each of said two optical axes of the microscope, said semitransparent light reflecting means reflecting a portion of the light from the object in the respective optical axis to said light reflecting means while said light reflecting means reflects the light into said optical axis of said camera body when the same is rotated to receive the light from either of said semitransparent light reflecting means.

Claim 7

Device according to claim 1, wherein said optical path switching means is detachable from the microscope together with said camera body.

Claim 8

Device for taking stereoscopic photograph in a stereoscopic microscope having two optical axes in each of which an objective lens and an ocular are optically arranged for the microscopic observation of an object therethrough, said two optical axes forming a parallax angle therebetween so that stereoscopic observation of the object is achieved when the same is viewed simultaneously through said ocular in each of said two optical axes, wherein the improvement comprises a camera body having a pair of optical axes which are located in parallel to each other in symmetry with respect to said two optical axes of the microscope and adapted to have a film loaded therein, and a pair of beam splitting means each including a semitransparent light reflecting means and a light reflecting means, said semitransparent light reflecting means in each of said pair of beam splitting means being located in the respective optical axes of the microscope so as to reflect a portion of the light from the object in the respective optical axes while said light reflecting means in each of said pair of beam splitting means is so located as to reflect the portion of the Light reflected by said semitransparent light reflecting means toward the respective optical axes of said camera body, thereby permitting a pair of stereoscopic photographs of the object to be obtained simultaneously on said film while permitting the simultaneous stereoscopic observation of the object.

Claim 9

Device for taking stereoscopic photograph in a stereoscopic microscope having two optical axes in each of which an objective lens and an ocular are optically arranged for the microscopic observation of an object therethrough, said two optical axes forming a parallax angle therebetween so that stereoscopic observation of the object is achieved when the same is viewed simultaneously through said ocular in each of said two optical axes, wherein the improvement comprises a camera body having a pair of optical axes which are located in parallel to each other in symmetry with respect to said two optical axes of the microscope and adapted to have a film loaded therein, and a pair of beam splitting means each including a semitransparent light reflecting means and a light reflecting means, said semitransparent light reflecting means in each of said pair of beam splitting means being located in the respective optical axes of the microscope so as to reflect a portion of the light from the object in the respective optical axes while said light reflecting means in each of said pair of beam splitting means is so located as to reflect the portion of the Light reflected by said semitransparent light reflecting means toward the respective optical axes of said camera body, thereby permitting a pair of stereoscopic photographs of the object to be obtained simultaneously on said film while permitting the simultaneous stereoscopic observation of the object.

Claim 10

Device according to claim 7, wherein the plane in which said pair of optical axes of said camera body are offset from the plane including said two optical axes of the microscope so as to facilitate the observation of the object without interference with said camera body, an angle being formed between the plane including said pair of optical axes of said camera body and the plane including said two optical axes of the microscope such that the rotation of each of the images on said film about the center thereof which is caused by the parallax angle between said two optical axes and the deviation of the light in each of said two optical axes out of the plane including the same is compensated for.
