Title: Ultraviolet torch mainly to polymerize dental plastic fillings - which uses optically filtered beam from incandescent filament low voltage lamp
Inventor: NATH GUENTHER DR
IPC: G02B6/42
Filed: 1976-11-02
Abstract: Hand held, UV ray torch is mainly for density. The torch uses an incandescent filament lamp of >=15 watts power to give light emission with a colour temp. >=3150 degrees K. Light from the lamp is focussed in a solid angle of >=6 steradians, converging towards a focal point via a thin dielectric filter. The filter separates mainly UV radiation of 330-400 mm. from mainly visible and infrared radiation. The mainly UV radiation is directed towards a focal point inside an optical conducting rod transparent to UV light and made of material with a numerical refractive opening of >=0.34. A second filter is placed in the beam between the first filter and the conducting rod, to eliminate residual visible and infrared rays. A current of cooling air is blown through the torch casing. The lamp is pref. of the low voltage, tungsten-halogen type. Used for localised application partic. in dentistry to polymerise plastic fillings etc. e.g. pellets of methyl methacrylate. The torch achieves full power within 0.3-3.0 seconds of switching on. Intensity of radiation remains constant until failure of the lamp. Replacement lamps are very much cheaper than mercury discharge lamps.
