FIELD: measurement equipment.SUBSTANCE: invention relates to laser equipment, to equipment of laser range finding. The laser range finder comprises a receiving device and a transmitting device, including a lens of a radiator and a laser radiator, the equivalent glow body of which with dimensions A×B is located in the focal plane of the radiator lens. The radiator lens comprises the first cylindrical component with the focus distance f?B/?, the generatrix of the cylinder of which is perpendicular to the minimum dimension B of the glow body, and the second cylindrical component with the focus distance f, the generatrix of the cylinder of which is perpendicular to the maximum dimension A of the glow body. Distances from cylindrical components to the equivalent glow body are equal to lfor the first cylindrical component and lfor the second one. The first cylindrical component has the second cylindrical profile, perpendicular to its first cylindrical profile and providing for focus distancebesides, the distance l=f-?f, distance l?L, focus distancesandwherel=(l-l), L - maximum permissible dimension of the radiator lens along its longitudinal axis, ? and ? - angular dimensions of the remote object, corresponding to the maximum A and minimum B dimensions of the equivalent glow body, ?f - distance between the main planes of the first and second cylindrical profiles of the first cylindrical component.EFFECT: provision of the possibility to reduce dimensions of an optical system of a radiator without reduction of capacity of output radiation and without increase of range finder mass.4 dwg |
