Abstract
An automatic focusing device for microscopes comprising nozzles arranged around the individual objective lenses, a gas feed pipe attached to the arm or the similar member of the microscope, and a coupler arranged in or near the objective lens switching device and used for connecting said gas feed tube to said nozzle, said automatic focusing device being adapted in such a manner that when objective lenses are switched from one to another to be used for microscopy by rotating said objective lens switching device, the nozzle arranged around the objective lens to be used for microscopy is connected to said gas feed tube, whereby the gas supplied through said gas feed tube passes through said coupler and is injected from said nozzle for focusing the objective lens to be used for microscopy.
Claims9
An automatic focusing device comprising a rotatable objective lens switching device equipped with a plural number of objective lenses, nozzles respectively arranged in the vicinity of said objective lenses and couplers respectively connected to said nozzles;
- and a gas feed tube connectable to any one of said nozzles through said any one of said couplers to supply gas into said any one of said nozzles thereby to focus, said automatic focusing device being adapted in such a manner that when one of the objective lenses is switched to another to be used for microscopy by rotating said objective lens switching device, said gas feed tube is connected to said any one of said nozzles, arranged in the vicinity of any one of said objective lenses to be used for microscopy through any one of said couplers, whereby the gas supplied through said gas feed tube passes through said any one of said couplers and is injected from said any one of said nozzles arranged in the vicinity of any one of said objective lenses to be used for microscopy to bring said any one of said objective lenses to be used for microscopy in focus condition.
