Abstract
The first-order Double-Gauss 4 element objective arrangement derived from a triplet type by splitting the central negative element is discussed. The Petzval sum of the lens system was chosen and calculated. With desired axial color, glasses will be selected and axial color calculated. By using the aspherical coefficients, we discuss the aberrations compensation. Following the design procedures to design a camera objective, the lens data after optimization and the MTF curve are presented.
