Embodiment Construction

[0030] figure 1 with figure 2 Shown is the first embodiment of the prism in the present invention, including a top surface, a bottom surface and a side surface, the top surface is the incident surface, and in this embodiment, the top surface includes two mutually perpendicular semi-transmissive and semi-reflective surfaces S2, S4, the semi-transmissive and semi-reflective surfaces S2, S4 form an angle of 45° with the incident laser light (not shown in the figure), the bottom surface S6 is perpendicular to the incident laser light and is connected to the semi-transmissive and semi-reflective surfaces S2, S4 Intersect at an included angle of 45°, and the bottom surface S6 is a total reflection surface. It also includes full-transmission sides S3 and S5 perpendicular to the bottom surface S6, and the edge part plane of the incident laser is parallel to the full-transmission sides S3 and S5 and is irradiated along the outside of the full-transmission sides S3 and S5. The transm...

Abstract

The invention relates to a prism and a multi-laser generating instrument with the same, wherein the prism is used for converting incident lasers into multiple lasers and comprises a top surface, a bottom surface and a side surface, and the top surface is an incident surface and comprises a semi-transmission and semi-reflection surface forming an included angle of 45DEG with the incident laser; the bottom surface is perpendicular to the incident laser, and one part of the bottom surface, which is used for receiving the transmission laser of the semi-transmission and semi-reflection surface, isa full-reflection surface; and the side surface comprises a full-transmission surface which is parallel to the incident laser and opposite to the semi-transmission and semi-reflection surface. The prism and the multi-laser generating instrument with the same overcome the defect of poor colinearity of the traditional multi-laser generating instrument.

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. [0003] U.S. Patent Documents US6154319, US6542304 and US6563646 disclose a prism respectively. The prisms in the three documents all adopt the pri...
