Abstract

Arrays of small lenses have been used in many aspects of optical recording and the purpose of this paper is to describe some examples that have been realized using lenses made at the UK National Physical Laboratory. We have produced simple lenses ranging from 50 micrometers to 400 micrometers in diameter with aperture ratios of f/1 and larger and in arrays up to 120 mm X 120 mm. The lenses are formed in layers of photoresist, making use of surface tension forces to shape the refracting surface when the resist is heated to melting point. Applications range from 3D imaging to beam steering and matching of optical arrays.
