Paper Abstract

A hybrid optical system containing one binary optical element and four refractive lenses is shown to be very useful for long distance photography. The system has the ability of correcting secondary spectrum as well as the five monochromatic primary aberrations and some higher order aberrations. The image performance of the system is diffraction-limited for both axial and off-axial images with focal length 1000 mm, F number 8 and field angle 3.5 degree(s), and it is light weight. Further advantages include using only the most common optical glasses, BK7 and F3 in Schott catalog.
