Abstract
A cylindrically shaped coil of resistance wire constitutes a source of infrared radiation which is located within a reflector comprised of a curved reflector section having a reflecting surface shaped to resemble an axially bisected rotationally symmetrical paraboloid, and a cylindrical reflector section which extends from an open side of the curved reflector section. The focal points of the reflecting surface are located on a circle which coincides with the outer circumference of the cylindrically shaped coil.
