DEVICE FOR TREATING BIOLOGICAL OBJECTS WITH LASER RADIATION Russian patent published in 1998 - IPC

FIELD: medical engineering. SUBSTANCE: device has laser light source connected to power supply source, cylindrical casing being quartz tube with end face walls covered with reflecting lining from inside. Semiconductor lasers are mounted on both end faces of the cylindrical quartz tube. Clarifying coating is applied to the inner surface of the tube. It is distributed as heterogeneous layer to improve uniform properties of radiation supply. Laser crystal is fixed on the tube in a manner that it plays the role of light guide and heat- removing unit at the same time. Reflecting coating of the end faces have spherical concave shape. End face surface has diffuse reflection properties. EFFECT: small size; uniform illumination of treated surface. 8 cl, 1 dwg
