Abstract
In this paper, we describe the basic principle and aberration properties of both single-element and two-element catadioptric magnifiers which have been designed and fabricated. These magnifiers are capable of producing visual magnification of 15 to 20 times with large eye-relief, and they are useful for reading microfiche having frame sizes of 16 mmX12 mm and 12 mmX9 mm. It has been found that by changing the shape of the single-element catadioptric magnifier, field curvature and distortion can be improved by considerable amounts. A much better improvement has, however, been obtained with the two-element system.
