Abstract
The invention discloses a student experimental laser comprising a housing in which laser point light sources are disposed. Beam expanding lenses are arranged in front of the laser point light sources. The side surface of each beam expanding lens is equipped with an up-down concave-convex mirror surface. Laser point light source buttons are arranged on the surface of the housing. The up-down concave-convex mirror surface is provided with five peaks so that multiple light sources can be expanded to linear light sources. The beam expanding lenses are arranged in front of the laser point light sources and the side surface of each beam expanding lens is equipped with the up-down concave-convex mirror surface. Thus, light emitted from the laser point light sources is irradiated to the mirror surface on the side surfaces of the beam expanding lenses. When the light passes through the up-down concave-convex mirror surfaces, the point light sources are diffused to be linear light sources on the up-down concave-convex mirror surfaces and the light are projected through the lenses. Further, the multiple linear light sources can be in parallel. Therefore, an optical experiment can be smoothly completed.
Description
Technical field
The present invention relates to a kind of laser.
Background technology
Student will use light source when doing optical physics experiment, and laser is due to can to a direction straightline propagation, so laser just becomes and does optical physics and realize optimal light source.All very little owing to doing the laser power of testing, and be all point-source of light, and do when testing and require as line source, so how laser point light source is become line source, and many line sources can keeping parallelism, and this becomes problem demanding prompt solution.
Summary of the invention
The object of this invention is to provide and a kind of laser point light source is become line source, and many line sources can the student experimenting laser of keeping parallelism.
Technical scheme of the present invention is as follows:
A kind of student experimenting laser, comprise shell, be provided with laser point light source in shell, be provided with extender lens before each laser point light source, the side of extender lens is provided with the concavo-convex minute surface of dipping and heaving; Described case surface is provided with laser point light source button.
The concavo-convex minute surface of described dipping and heaving is provided with 5 crests; Such energy ensures that multiple light source is by expanding into line source.
The jog semicircular in shape of described minute surface, its radius is 0.5-1.0mm.
Three laser point light sources are provided with in described shell.
Laser of the present invention is by arranging extender lens at each laser point light source, extender lens side is arranged the minute surface that dipping and heaving is concavo-convex, penetrate on the minute surface of extender lens side when laser point light source emits, when minute surface concavo-convex by dipping and heaving, point-source of light is diffused into line source on male and fomale(M&F), and scioptics project away, and many line sources can keeping parallelism; This ensure that Experiments of Optics can complete smoothly.

Fig. 2 is the schematic diagram of the extender lens of laser of the present invention.
Fig. 3 is the left view of Fig. 2.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail:
As shown in Figure 1, 2, 3, a kind of student experimenting laser, comprise shell 1, be provided with laser point light source in shell 1, the present embodiment arranges three laser point light sources, is provided with extender lens 2 before each laser point light source, the side of extender lens 2 is provided with the concavo-convex minute surface of dipping and heaving 3, be similar to wavy minute surface, shell 1 surface is provided with laser point light source button 4, and laser point light source button 4 is used for controlling the opening and closing of laser point light source.
The concavo-convex minute surface 3 of dipping and heaving is provided with 5 crests, i.e. 5 convex surfaces, 4 concave surfaces, can ensure that multiple light source is by expanding into line source like this; The jog semicircular in shape of minute surface simultaneously, its radius is 0.5-1.0mm; Easy demoulding when can ensure like this to produce, what make again light source expand is very well.Three laser point light sources become three parallel lines light sources after extender lens, can in the scope of 100cm keeping parallelism, be enough to various Experiments of Optics.
