Abstract
A composite prism based on an isosceles prism and a laser ranging telescope includes a first prism, a second prism, a third prism and a compensating prism. The first prism is an isosceles prism with three reflecting surfaces, the second prism is a roof prism, the third prism is a half-penta prism, and the compensating prism is a wedge prism. Through the composite prism, a telescope observation system, a laser emission system, a laser receiving system and a sighting and display system are reasonably integrated, so that a telescope features diversified performance and structural style, small size and convenient to carry.
