Problems solved by technology

However, when the microscope barrel is disassembled and the reticle stop mechanism is removed as described above, since the reticle stop mechanism is unnecessary, it is necessary to disassemble the microscope again in order to attach the reticle stop mechanism to its original position. lens barrel, so the reticle stop mechanism cannot be easily installed

Embodiment Construction

[0032] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings. In addition, this invention is not limited to this embodiment.

[0033] FIG. 1 is a perspective view showing a microscope barrel of the present invention, and FIG. 2 is a schematic cross-sectional view of the microscope barrel shown in FIG. 1 . The microscope lens barrel of the present embodiment is mounted on a microscope main body having an object stage on which a sample to be observed is placed, and is constituted as a binocular lens barrel as follows. The observation light of the microscope is divided into two parts, so that the divided observation light is incident on the two eyepieces, and the same image can be observed with both eyes, and the microscope lens barrel has a Sidento that can adjust the distance between the two eyes, that is, the distance between the eyes. Husband-type eye distance adjustment mechanism.

[0034] As shown in FIGS. 1 t...

Abstract

A microscope lens barrel includes a lens barrel section in which a fixed tube is fixed to a lens barrel body, one of two holding tubes arranged parallel to and equidistant from a center axis of the fixed tube is provided to be movable without changing a distance from the center axis, and an optical system is placed to maintain directions of optical axes so that two optical paths split by transmitting and reflecting an incident optical path are always aligned with center axes of the holding tubes, and a reticle anti-rotation unit in which a reticle plate is placed so that a plane on which a reticle is provided is perpendicular to the center axis of the movable holding tube and which is removably mounted to the fixed tube and the movable holding tube in a state where a holding mechanism holding a direction of the reticle plate on the center axis to the microscope body is integrated.

Description

technical field [0001] The present invention relates to a microscope lens barrel constituting a binocular lens barrel and having a Sidentoff type eye distance adjustment mechanism. Background technique [0002] A microscope barrel is mounted on a microscope body having a stage for placing a sample as an observation object, and observation light incident from an objective lens provided in the microscope body is incident on an eyepiece held on the barrel itself, The image is formed in the human eye via the eyepiece. The microscope barrel has a binocular barrel that divides the light path incident from the objective lens into two through the optical system, and makes the branched light paths enter the eyepieces respectively, so that the same image can be observed in both eyes. Furthermore, the microscope barrel constituting the binocular barrel has an eye distance adjustment mechanism for adjusting the distance between eyepieces according to the distance between the user's eye...
