Embodiment Construction

[0011] The present invention will be further described below in conjunction with the accompanying drawings.

[0012] The laser and visible light spectroscopic erecting prism group provided by the present invention includes a roof prism 1, and also includes a compound prism composed of two prisms 2 and 5 glued together to form a visible light path B together with the roof prism 1, and a spectroscopic film is arranged on the glued surface 4. A laser emitter 3 is arranged opposite to the reflective surface of 2 in the compound prism, the axis (optical path) A of the laser emitter 3 and the visible light axis B of the compound prism are relative to the glued surface between the compound prisms (i.e. the spectroscopic film 4) into a mirror image. Wherein, the reflective surface of the prism 2 in the composite prism and the exit surface of the prism 5 constitute an included angle a of 60°; The included angle b is 30°; the light-splitting film 4 adopts a conventional light-splitting...

Abstract

The invention provides a laser and visible light light-splitting erecting prism group comprising a rigging prism and a composite prism, wherein the composite prism is glued by at least two prisms and forms a visible light path together with the rigging prism, the glue surface of the composite prism is provided with a spectro-film, a laser is arranged at the position opposite to the reflection surface of the composite prism, and a laser axis and the composite prism visible light path form mirror images relative to the glue surface of the composite prism. Therefore, the prism group has both image erecting function and light-splitting function, and can respectively extract visible light information and laser information and respectively process all the information; and optical products, such as telescopes, cameras, and the like, which apply the prism group with image erecting function and light-splitting function, can utilize visible light to do observation or camera shooting, utilize laser to measure distances, and the like, thereby expanding the function of the products and being more convenient for users to use.

Description

technical field [0001] The invention relates to a prism group, in particular to an erecting prism group capable of splitting laser light and visible light, and belongs to the technical field of optical instruments. Background technique [0002] The erecting prisms currently used in visual observation or imaging optical systems are usually composed of roof prisms and isosceles prisms. Its role in the optical path is to invert the imaging of the front optical system such as the objective lens and transmit it to the rear optical system such as the objective lens, so it only has the function of a positive image. In the actual application of the erecting prism group, people also hope that the erecting prism group also possesses the spectroscopic function while possessing the erecting function, so that the optical instruments such as telescopes and video cameras using this prism group with the erecting function and the spectroscopic function Optical products such as optical produ...
