Abstract

According to some embodiments of the present invention, a fine focus microscope includes an objective lens for collecting light from an object being imaged, and a tube lens for forming a first image from light received from the objective lens. The fine focus microscope further includes a fine focus lens for forming a second image from the first image, and an eyepiece for forming a third image from the second image, wherein the third image is viewable by a user. The fine focus microscope further includes a field lens for directing light from the second image to the eyepiece, and a positioning system mechanically coupled to the fine focus lens, the eyepiece, and the field lens. The positioning system changes a position of the fine focus lens, the eyepiece, and the field lens with respect to the objective lens to provide a change in focus of the object being imaged.

Dependent claims

A fine focus microscope comprising:

an objective lens that collects light from an object being imaged;
a tube lens that forms a first image from light received from said objective lens;
a fine focus lens located between the tube lens and an eyepiece, wherein the fine focus lens forms a second image from said first image;
wherein the eyepiece forms a third image from said second image, wherein said third image is viewable by a user;
a field lens directs light from said second image to said eyepiece;
a positioning system mechanically coupled to said fine focus lens, said eyepiece, and said field lens;
a tube, wherein said objective lens, tube lens, fine focus lens, field lens, and eyepiece are disposed within said tube,
wherein said positioning system changes a position of said fine focus lens, said eyepiece, and said field lens with respect to the first image to provide a change in focus of said object being imaged while a position of the objective lens is unchanged;
and
wherein said fine focus lens provides a magnification between 2X and 100X.
