  • Lamp assemblies with compensating rings between lamp bodies and output windows with different rates of thermal expansion
    Publication number: 20020185976
    Abstract: A ring mounted by sealant between a lamp body and an output window has a coefficient of thermal expansion intermediate to those of the lamp body and output window, thus to compensate for differing rates of thermal expansion and contraction of the lamp body and output window. A ring may be of solid metallic material, and may be solid or adapted to flex between the body and window.

  • Filament lamp infrared source
    Patent number: 5438233
    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.

  • Gas discharge light source
    Patent number: 5055979
    Abstract: A miniature gas discharge lamp having a direct physical connection with an end portion of an external optical fiber. Light generated within the lamp is directed against an end face of the optical fiber to cause light rays to travel within and along the fiber. The lamp has an elongated straight passage for containment of a radiation-producing gas, the passage being axially aligned with the optical fiber so that substantially all of the photon energy generated within the passage is optically connected to the end face of the fiber.
