“…Extensive investigations by Russian researchers over the past few decades into the nature and origin of impurities in ChGs [343,[349][350][351][352][353][354][355] have led to a reduction in optical loss <1 dB∕m in fibers from the As-S, As-Se, and As-S-Se systems (except for several IR absorption bands caused by stubborn impurities [356]). Using the double-crucible method, step-index As-S fibers were fabricated in the early 1990s [158], followed by step-index As-Se-Te and As-S-Se glass fibers with minimal optical losses of 0.15 dB/m at 6.6 μm and 0.06 dB/m at 4.8 μm, respectively [357].…”

Infrared (IR) fibers offer a versatile approach to guiding and manipulating light in the IR spectrum, which is becoming increasingly more prominent in a variety of scientific disciplines and technological applications. Despite well-established efforts on the fabrication of IR fibers in past decades, a number of remarkable breakthroughs have recently rejuvenated the field-just as related areas in IR optical technology are reaching maturation. In this review, we describe both the history and recent developments in the design and fabrication of IR fibers, including IR glass and single-crystal fibers, multimaterial fibers, and fibers that exploit the transparency window of traditional crystalline semiconductors. This interdisciplinary review will be of interest to researchers in optics and photonics, materials science, and electrical engineering.

The paper deals with certain factors affecting the use of thermocouples for psychrometric purposes, and considers some of the advantages possessed by inst" ments of this type. An investigation is made for the purpose of determining the manner in which the wet-bulb depression depends on the degree of ventilation, the diameter of the wire, the thickness and length of the water film covering the junction of the wet thermocouple, and the relative positions of the wet and dry thermocouples. It is shown that the need for forced ventilation of the wet thermocouple decreases as the diameter of the wetted wire is diminished. A typical example is given showing that for a psychrometer composed of nichrome and constantan wires of 40 s.w.g. mounted in a still air enclosure, the percentage relative humidity derived from its readings is only two or three units greater than that given by a fully ventilated instrument, when psychrometric tables appropriate to the latter condition are usqd in each instance. . -9 I.
