Differential interference contrast microscope using non-uniformly deformed plastic birefringent components |
| abstract |
In a differential interference contrast microscope, including a beam splitter and a compensator beam splitter, each of the beam splitters and the compensator comprise at least one non-uniformly deformed plastic birefringent component exhibiting linearly graded optical retardation between the ordinary and the extraordinary transmitted rays in one direction across the aperture and constant retardation in the orthogonal direction. The splitter and compensator may comprise a single unit for a reflected light microscope. |
