Abstract Reflecting microscope objective comprising a major concave reflecting mirror and a minor convex reflecting mirror coaxially located in spaced relation therefrom so that the light from an object is reflected by the major concave reflecting mirror toward the minor convex reflecting mirror to be again reflected thereby toward means such as eyepiece means of a microscope on which the reflecting microscope objective is mounted. A plane reflecting mirror is provided rearwardly of the minor convex reflecting mirror in spaced relation therefrom and the major concave reflecting mirror is located at the object side with respect to the plane reflecting mirror so that the light from the object is first received by the plane reflecting mirror so as to be reflected toward the major concave reflecting mirror, the light received thereby being again reflected toward the plane reflecting mirror which in turn reflects the thus received light to the minor convex reflecting mirror so as to be reflected toward means such as the eyepiece means.
Reflecting microscope objective comprising a major concave reflecting mirror and a minor convex reflecting mirror coaxially located in spaced relation therefrom so that the light from an object is reflected by said major concave reflecting mirror toward said minor convex reflecting mirror to be again reflected thereby toward means such as eyepiece means of a microscope on which the reflecting microscope objective is mounted, wherein the improvement comprises a plane reflecting mirror located rearwardly of said minor convex reflecting mirror in spaced relation therefrom, said major concave reflecting mirror being located at the object side with respect to said plane reflecting mirror in spaced relation therefrom thereby permitting the light from the object to be reflected by said plane reflecting mirror toward said major concave reflecting mirror to thereby be reflected again toward said plane reflecting mirror so that the light received by said plane reflecting mirror is reflected toward said minor convex reflecting mirror so as to be reflected again toward means such as the eyepiece means of the microscope.
