Abstract

A range of practical nonimaging designs for optical fiber applications is presented. Rays emerging from a fiber over a restricted angular range (small numerical aperture) are needed to illuminate a small near-field detector at maximum radiative efficiency. These designs range from pure reflector (allmirror), to pure dielectric (refractive and based on total internal reflection) to lens-mirror combinations.Sample designs are shown for a specific infrared fiber-optic irradiation problem of practical interest.Optical performance is checked with computer threeldimensional ray tracing. Compared with conventionalimaging solutions, nonimaging units offer considerable practical advantages in compactness and ease of alignment as well as noticeably superior radiative efficiency.
