Selection of Glasses for Achromatic Doublets with Reduced Secondary Spectrum. II. Application of the Method for Selecting Pairs of Glasses with Reduced Secondary Spectrum.
The method for selecting pairs of glasses for thin aplanatic achromatic doublets and cemented achromatic doublets with a reduced secondary spectrum, presented in Part I, is applied to the design of two optical systems. The first is a Lister-type 10x microscope objective with a numerical aperture of 0.25 working in the visible band. The second is a camera f/7.5 working in the near-IR spectral band, 0.8521 mum < lambda < 2.3254 mum, of a spectrograph for the San Pedro Martir Observatory in Ensenada, México. Improvement in the performance of both optical systems is shown.
