Abstract

Discrete phase kinoform lenses, also known as DOEs1, have been designed and fabricated on quartz substrates for operation at 1.064 micrometers (aperture diameters were 8 mm). Pairs of these lenses were arranged in a Keplerian geometry (Figure 1). The individual elements were measured separately and have already been reported1,2. An F/8 lens, manufactured by direct laser write, followed by a two-level or binary F/4 lens, manufactured by a photolithographic technique, were measured. Theoretical studies were also made of F/4-F/2 and F/2-F/1 combinations.
