English abstract:

A method of glass selection for the design of apochromatic optical systems with reduced chromatic aberration is presentrd. This method is based on the glass maps by using a glass database (Ohara glass) and an optical design program (Oslo) to help the optical designer to select optical glass types in a more efficient way. "Active" glass maps can be used to compare glasses for special properties and to change glasses in the optical design process. The important roles of refractive index and Abbe number as well as partial dispersion will be considered to drawing the Ohara glass map and then using computer program Oslo to aid in the design of a lens and the validation results. The goal for this paper is to make glass selection easier to understand.
