Abstract
A Lister objective of NA 0.25 and 10×, stabilized against chromatic variation for a wavelength of 405 nm is designed. We develop a new solution for stabilizing a cemented doublet that has specified axial thicknesses. Using the new method, we can easily obtain a useful design for some practical purpose. At the initial design stage, two cemented doublets corrected independently are used. The stabilizing conditions for the whole system are maintained during optimization. The final design of the Lister objective shows that the chromatic variation of EFL, BFL, and RMS wavefront errors are very small at the 405-nm wavelength, as expected.
