Abstract
We develop a range of practical nonimaging devices for optical fiber applications where rays emerging from a fiber over a restricted angular range (small numerical aperture) must illuminate a small near-field detector at maximum radiative efficiency. These designs range from pure reflector (all-mirror), to pure dielectric (refractive and based on total internal reflection), to lens-mirror combinations. Sample designs are presented for a specific infrared fiberoptic irradiation problem of practical interest. Optical performance is checked with computer 3D raytracing. Compared to conventional imaging solutions, our new nonimaging units offer considerable practical advantages in compactness and ease of alignment, as well as noticeably superior radiative efficiency.
