Abstract

PURPOSE: To suppress coma aberrations and chromatic aberrations and obtain the magnifying lens through the use of ordinary glass by separating and disposing three sets of doublet lenses bonded with positive and negative lenses and satisfying the specified lens condition formulas.
CONSTITUTION: When viewed from the object side, the doublet lens I is disposed in the order of a negative lens and a positive lens, the doublet lens II in the order of a positive lens and a negative lens and the doublet lens III in the order of a positive lens and a negative lens. Curvature of field, coma aberration and distortion aberation are suppressed by conditions (1), (2), (3). Correction of chromatic aberration is accomplished through the use of ordinary glass by conditions (4), (5).
