Paper Abstract

We have designed and built a number of doublet and triplet lenses intended for focussing laser light. The wavelength range extends from 220 nm to 1550 nm. An ordinary achromat, sometimes called a telescope objective, is suitable for some applications, but its cemented surface will not tolerate high irradiance levels. We discuss the performance of the designs at widely spread wavelengths and show which types of designs can be used without refocussing (achromatic) and which types perform satisfactorily only with refocussing as the wavelength is changed. In particular, we describe the cemented telescope objective, the air-spaced telescope objective, a cemented doublet without axial color correction, an air-spaced objective of a single glass type, an air-spaced doublet for high power lasers, and a three element lens.
