Crystals and light guides for the mid-infrared spectral range

IR Thermographic System Supplied with an Ordered Fiber Bundle for Investigation of Power Engineering Equipment and Units

“…(1) producing raw materials by the thermal-zone crystallization-synthesis technique, which enables to carry out both synthesis and purification simultaneously [6]; (2) growing single crystals of silver halides using the Bridgman technique based on directional crystallization [7]; (3) obtaining cylindrical billets by means of mechanical treatment; (4) manufacturing polycrystalline fibers using extrusion technique [8];…”

“…[1][2][3]. One more possible application sphere of IR thermography is power engineering [4][5][6]. IR thermography is one of the most attractive and successful techniques, which allows detecting the object's surface and subsurface defects remotely without harmful radiation effects of other technologies (such as X-ray imaging).…”

Highly transparent ceramics for the spectral range from 1.0 to 60.0 µm based on solid solutions of the system AgBr–AgI–TlI–TlBr

“…For two decades Ural Federal University has carried out research in the field of exploring and creating a new photonics' element base for optical and laser instrumentation, crystals [10,11,[25][26][27][28][29][30][31][32][33] . The key materials of our research are solid solutions of silver and monovalent thallium halides, such as AgCl-AgBr, AgBr-TlBr 0.46 I 0.54 , AgBr-TlI, AgCl-AgBr-TlBr 0.46 I 0.54 , AgCl-AgBr-TlI, AgCl-AgI, AgBr-AgI, and AgCl-AgBr-AgI.…”

“…These materials are transparent from visible to far IR, as well as in the terahertz (THz) range. Among other things, the materials have high ductility, which makes it possible to obtain windows and lenses from them by hot pressing, as well as by extrusion of fibers for the range of 2.0-25.0 μm [11,[27][28][29][30][34][35][36][37][38][39][40] .…”
