Abstract: The microwave supplied lamp has a tube (2) within a discharge cavity (1) at the point of highest field strength. The presence of the tube changes the field within the space. The central region (3) of the lower wall is formed by a wire mesh (3). A waveguide (4) is coupled to the space and has a slot shaped coupling aperture (5). The waveguide can also be located on the top surface. The discharge tube is made of quartz and has reflectors (8, 8') on both sides. The end of the unit has a location provided for a magnetron unit (6), supplying the lamp with energy. USE/ADVANTAGE - For incoherent optical radiation. Covers wide wave-band, from ultraviolet to visible or infrared range. Provides uniform discharge along wave-band. Lamp is uniformly excitable.
