Abstract
A microscope assembly includes an objective lens and an infinite conjugate tube lens. The effective focal length of the objective lens is not greater than 80 mm. The numerical aperture of the microscope is 0.14 or more. The microscope exhibits a magnification of 2× or more.
Claims20
A microscope assembly kit, comprising:
- (a) multiple diffraction limited lens assemblies each having an unique combination among said lens assemblies of effective focal length and numerical aperture;
- (b) a microscope housing configured to contain combinations of said lens assemblies each forming a microscope assembly that includes an objective lens and a tube lens disposed on object and image sides, respectively, of an aperture stop;
- (c) wherein said microscope assembly is configured to form images with both (i) a numerical aperture equal to the numerical aperture of the objective lens, and (ii) a magnification equal to a ratio of effective focal lengths of the tube lens and the objective lens.
