Embodiment Construction

[0026] figure 1 It is a schematic structural diagram of the prism of the first embodiment of the present invention. Such as figure 1 As shown, the prism of the present invention includes a total transmission bottom surface O1 perpendicular to the incident laser M, a top surface O2 parallel to the bottom surface O1, and a total transmission side O3 perpendicular to the bottom surface O1, and the bottom surface O1 is the incident surface . The prism also includes a semi-transmissive and semi-reflective surface O4 at an angle of 45° with the bottom surface O1, and the semi-transmissive and semi-reflective surface O4 divides the top surface O2 into two parts, wherein the semi-transmissive and semi-reflective surface O2 is received. The part of the laser light transmitted by the surface O4 is the total reflection part O5, and the other part is the total transmission part O6. The incident laser light M is irradiated on the fully transparent bottom surface O1, a part of which is t...

Abstract

The invention relates to a prism and an instrument having the prism and generating multi-beam laser. The prism is used for converting incident laser into the multi-beam laser and comprises a total-transmission bottom surface, a top surface and a total-transmission side surface, wherein the top surface is parallel to the bottom surface; the side surface is vertical to the bottom surface; the bottom surface is an incident surface; the prism also comprises a transflective surface which forms a 45-degree angle with the bottom surface; and the top surface is divided into two parts by the transflective surface, wherein the part which receives the laser transmitted through the transflective surface is a total-reflection surface and the other part is a total-transmission surface. The prism and the instrument having the prism and generating the multi-beam laser overcome the defects that a light beam is complex to calibrate and the cost is high in the conventional instrument generating the multi-beam laser, and provide the instrument which is simple to calibrate the light beam, has low cost and generates the multi-beam laser.

Description

technical field [0001] The invention relates to a prism and an instrument for generating multiple laser beams with the prism. Background technique [0002] In construction, horticulture and other industries, reference lines are indispensable for engineering. The traditional tools commonly used to establish reference lines are rulers, rulers, protractors, T-squares, spirit levels, and plumb bobs. As the scale of the project increases, these traditional tools are greatly limited due to their size and the inconvenience of manual operation. At present, instruments that generate multiple laser beams are mainly used in large-scale projects. Existing instruments that generate multiple laser beams mostly use multiple laser sources to generate multiple laser beams. Calibration, and the cost of using multiple laser sources is also high. US patent documents US6154319, US6542304 and US6563646 respectively disclose a prism, and the prisms in the three documents all adopt the principle ...
