Portable microscope having an illumination device, and microscope stage

If you were to search for Portable microscope having an illumination device, and microscope stage using relaxed search criteria, these patents would come up:

What is claimed is:

1. A portable microscope comprising: a stand that is constructed from a first housing shell and a second housing shell; a height-adjustable microscope stage which is carriedby the stand; a base part that closes the first and the second housing shell at the bottom, wherein the microscope stage forms a unit from a sample support part, a cylindrical guide part, and a base; the base of the microscope stage carries anillumination module; and wherein the sample support part, the cylindrical guide part, and base are adhesively bonded together into the unit, an energy source is provided in the base part of the stand, the energy source being a battery or rechargeablebattery, and an on/off switch is associated with the microscope stage in such a way that when the microscope stage is lowered, delivery of power from the energy source to the illumination module is interrupted; and when the microscope stage is raised,delivery of power from the energy source to the illumination module is effected.

2. A portable microscope comprising: a stand that is constructed from a first housing shell and a second housing shell; a height-adjustable microscope stage which is carried by the stand; a base part that closes the first and the secondhousing shell at the bottom, wherein the microscope stage forms a unit from a sample support part, a cylindrical guide part, and a base; the base of the microscope stage carries an illumination module; and wherein the sample support part, thecylindrical guide part, and base are adhesively bonded together into the unit, and the microscope stage is operatively arranged to be partially inserted into the stand as defined by the first and the second housing shell, and the cylindrical guide partof the microscope stage slides inside the stand.

3. The portable microscope as defined in claim 2, wherein an elastic element, which exerts a return force on the microscope stage in order to pull the microscope stage into the stand, is joined to the base of the microscope stage and to thestand.

4. A microscope stage for a portable microscope, comprising: a sample support part, a cylindrical guide part and a base and an illumination module is carried by the base and wherein the sample support part, the cylindrical guide part, and baseare adhesively bonded together into a unit, and an on/off switch is associated with the microscope stage in such a way that when the microscope stage is lowered, delivery of power from an energy source to the illumination module is interrupted; and whenthe microscope stage is raised, delivery of power from the energy source to the illumination module is effected.

5. The microscope stage as defined in claim 4, wherein the energy source is a battery or rechargeable battery.

6. A microscope stage for a portable microscope, comprising: a sample support part, a cylindrical guide part and a base and an illumination module is carried by the base and wherein the sample support part, the cylindrical guide part, and baseare adhesively bonded together into a unit, and the illumination module is a preassembled component and the base, the cylindrical guide part, and the sample support part are adhesively bonded to one another; and the illumination module is retained inthe guide part with a plastic ring and by means of the base adhesively bonded to the cylindrical guide part.
