Abstract
A lamp configuration particularly for infrared radiation provides an internal arrangement and environment adapted to overcome failure modes of prior art broad band infrared sources, and may incorporate optical elements including spectral filters and lenses enabling wavelength selection, beam shaping, external focusing, collimating, and wave front shaping. It also facilitates optical coupling to external devices including a rotating mirror, shutter and modulator devices.
