Embodiment Construction

[0018] The structural principle and working principle of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0019] Such as Figure 1 to Figure 3 As shown, the present invention is a periscope reflective prism, comprising an optical glass body 1, the optical glass body 1 is provided with a reflective bottom surface 11 and a first light-transmitting side surface 12 and a second light-transmitting side surface 13 connecting both sides of the light-reflecting bottom surface; The first light-transmitting side 12 and the second light-transmitting side 13 are symmetrical to each other, the tops are intersected and connected, and the angle a at the top is 110 degrees; the lower side of the reflective bottom 11 is provided with a silver-plated layer 14 and paint from the inside to the outside. Layer 15; the first light-transmitting side 12 and the second light-transmitting side 13 are respectively coated with an anti-reflect...

Abstract

The invention discloses a light-reflecting triangular periscope, comprising an optical glass main body, wherein the optical glass main body is provided with a light-reflecting bottom surface as well as a first light-transmitting side surface and a second light-transmitting side surface which are connected with two sides of the light-reflecting bottom surface; the first light-transmitting side surface and the second light-transmitting side surface are mutually symmetrical and are intersected and connected at the tops, and a top included angle is 110 degrees; a silver coating and a paint coating are respectively arranged on the lower side of the light-reflecting bottom surface from inside to outside; antireflection films are respectively plated on the first light-transmitting side surface and the second light-transmitting side surface. The light-reflecting triangular periscope has the advantages that a light reflection angle is difficult to deviate, the light transmittance is high and the light loss is small.

Description

technical field [0001] The invention relates to a triangular prism, in particular to a periscope reflective triangular prism. Background technique [0002] Submarines or other underwater equipment usually need to use periscopes during their work. Periscopes refer to devices that protrude from the water surface or protrude from the low-lying tunnels to spy on activities on the water surface or on the ground. Its structure is the same as that of ordinary ground telescopes, except that two reflectors are added to make the object light reflect twice and then turn to the eyes. [0003] The main part of the periscope is a long steel tube mast that can be raised to a height of more than 5 meters, with prisms and lenses installed at each end to reflect light. The prism in the periscope usually adopts a periscope reflective prism, but the existing periscope reflective prism still has the problems of light reflection angle deviation and poor light transmission.
