Apochromatic designs of lens systems utilizing two optical materials are described. A method of glass selection for apochromatic optical systems with reduced chromatic aberration is present. This method is based on the glass maps by using a glass database (Schott 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 , 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.
