LASER HAND-OPERATED PROTECTIVE DEVICE Russian patent published in 2003 - IPC

FIELD: applicable as an individual protective-illuminating means designed for illumination of objects and protective action at a threat of attack. SUBSTANCE: the device has a body accommodating at least two luminous radiators using semiconductor laser diodes or laser modules with a slit diaphragm, power unit with a monitoring system of intensity of luminous radiators and a function switch of luminous radiators. The device is provided with objective lenses according to the quantity of radiators installed in the optical axis of each radiator for their movement along the optical axis. The radiators are so installed in the body that their optical axes are parallel with one another and located in the same plane, the larger sides of the radiating ends of the radiating bodies of the laser radiators are parallel with one another and perpendicular to the plane of the optical axes of the objective lenses. The front focus of each objective lens is installed in the optical axis past or before the radiating end of the luminous body of the respective laser radiator at distances determined from the expression indicated in the claim. EFFECT: enhanced efficiency of use due to reduced loss of light and rational forming of the form of the light spot. 6 cl, 4 dwg
