This paper presents a survey of current work at Tel Aviv University on properties and applications of silver
halide infrared transmitting fibers. Various infrared spectral features of core-only fibers, extruded from
pure mixed halide crystals of composition AgClBr1(O < x < 1), are presented and discussed. In the best
fibers, total loss is as low as 0.15 dB per meter at a wavelength of 10.6 jim. The fibers can be repetitively
bent on a 5 cm radius without degrading the transmission, up to thousands of bends. Fibers witha smooth
core-clad structure have also been fabricated, but the optical losses are still relatively high. Novel
applications of these fibers in spectrophotometry and radiometry are described.
