Abstract

Providing a compact lightweight stereomicroscope securing a light weight necessary for carrying, capable of securing stability upon attaching a camera. The stereomicroscope includes a base 1 that places a sample thereon, a microscope body 9 having a pair of left and right observation optical systems for observing the sample and a photographing optical system that leads the light from the sample substantially corresponding to the focusing center of the observation optical systems to a imaging means 17, a column 3 that is disposed on the base 1 and supports the microscope body 9, a support means that supports the imaging means 17, and a connecting means 13 that rotatably connects the microscope body 9 to the column 3. An optical axis I of the photographing optical system becomes substantially parallel to a rotation axis O of the connecting means.

Claims9

Dependent claims

A stereomicroscope comprising:

an eyepiece portion;
a base;
a column that is vertically disposed from the base, the column being coupled to a support member that extends vertically from the base so that the column is movable along a lengthwise direction of the support member;
a microscope body that is attached to the eyepiece portion, is supported rotatably on an observer side of the column, has a rotation axis substantially perpendicular to the column and extending toward the observer, and is capable of being rotated, in the entirety of the microscope body, around the rotation axis selectively between an observation position and a storing position;
a support device that supports an imaging device and is supported on the opposite side of the column and the support member from the observer;
and
a tubular connecting member extending through an interior of the column between the microscope body and the support device, the connecting member being movable with the column and positioned in an upper portion of the column such that in a lowest position of the column relative to the base, the connecting member is positioned above the support member;
the microscope body including an imaging optical system and a roof prism so that light from a sample is reflected by the roof prism substantially perpendicularly and led through the imaging optical system to the imaging device, an optical axis of the imaging optical system being substantially coaxial with the rotation axis and extending in a direction away from the observer, the optical axis further extending across the column and the support member through the connecting member.

the microscope body having an imaging optical system that includes an objective lens and a reflection member, such that light from a sample passes through the objective lens and is reflected by the reflection member substantially perpendicularly and led through the imaging optical system to the imaging device, an optical axis of the imaging optical system being substantially coaxial with the rotation axis and extending in a direction away from the observer, the optical axis further extending across the column and the support member through the connecting member;
the microscope body further having an observation optical system that includes a pair of objective lenses through which light coming out from the sample is led to the eyepiece portion, the observation optical system having a pair of optical axes which are not coaxial with the optical axis of the light coming out from the sample and incident on the reflection member and which are inclined toward the observer;
and
the objective lenses of the observation optical system being inclined with respect to the respective optical axes of the observation optical system, thereby preventing inclination of an image of the sample caused by the pair of optical axes being inclined toward the observer.
