FIELD: research and laboratory equipment for optical investigations. SUBSTANCE: laboratory furnace designed for investigating high- temperature processes by means of optical devices has lined housing that accommodates heater, muffle, and two viewing ports. Lower viewing port is made in the form of transparent cylindrical rod mounted inside muffle for axial displacement to allow for passing directional light flux through specimen under investigation; rod is made of quartz glass. EFFECT: simplified design, facilitated visual examination of intrafurnace processes in passing light. 2 cl, 2 dwg
