ENERGY DISTRIBUTION TRANSFORMER USABLE IN OPHTHALMOLOGICAL LASER DEVICE Russian patent published in 2003 - IPC

FIELD: medical engineering. SUBSTANCE: device has energy density transformer and projecting objective. Flat phase plate is used as the energy density transformer. Spherical lens is used as the projecting objective. The flat phase flat plate has reflecting coating and local geometric shape change feature. The plate is set at an angle to the incident laser beam to enable one to control direction diagram width by changing inclination angle. The projecting objective is mounted in the angle of direction diagram of reflected divergent laser beam. EFFECT: ideally smooth Gauss energy distribution; adjustable laser beam energy density distribution shape. 1 dwg
