Abstract : The staircase lens is a novel type of diffractive optical element which is particularly useful in applications such as laser range finders, CD pickup heads, and other laser collimators. The staircase lens is particularly promising for these applications because it allows for a singlet to be simultaneously corrected for both chromatic aberration and thermal effects. Designs are presented in PMMA for visible applications and Germanium for infrared applications. (MM)
