Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of optical equipment, in particular to a six-laser beam emitting device. Background Art
[0002] Existing laser emitting devices all use a single light source to emit linearly or refract to form a unidirectional laser emission line. When six groups of light are needed to perform an operation, the existing equipment is assembled using six groups of laser light sources. In actual practice, the cost of the laser light source is relatively high, which in turn leads to the high cost of the laser emitting device. In addition, the arrangement of the six groups of laser light sources makes the entire device relatively power-consuming. Therefore, there is an urgent need to develop a six-laser beam emitting device with relatively low energy consumption and simple structure. Summary of the invention
[0003] In view of the above problems, the utility model provides a six-laser beam emitting device, which can complete the emission of at most six groups of parallel laser beams through two groups of lasers, thereby reducing costs and power consumption.
[0004] A six-laser beam emitting device, characterized in that it comprises:
[0005] Two groups of lasers, specifically a first laser and a second laser;
[0006] The transmission grating is a long strip structure, including an incident surface on one side and an exit surface on the other side;
[0007] and two groups of lenses, specifically a first lens and a second lens;
[0008] The first laser and the second laser are arranged at intervals along the long strip incident surface of the laser transmission grating, respectively; the emitted light beams of the first laser and the second laser are arranged perpendicular to the incident surface; the two groups of emitted light beams are respectively emitted after being diffracted by the transmission grating to form corresponding 0th order diffraction light, +1st order diffraction light and -1st order diffraction light; the first lens and the second lens are arranged at intervals along the long strip exit surface of the transmission grating, respectively; the incident surface of the first lens covers three groups of diffraction light formed by the diffraction of the first laser by the transmission grating; the incident surface of the second lens covers three groups of diffraction light formed by the diffraction of the second laser by the transmission grating; the first lens collimates the 0th order diffraction light, +1st order diffraction light and -1st order diffraction light corresponding to the first laser and emits three groups of parallel light beams; the second lens collimates the 0th order diffraction light, +1st order diffraction light and -1st order diffraction light corresponding to the second laser and emits three groups of parallel light beams.
[0009] It is further characterized by:
[0010] The first laser and the second laser are the same laser;
[0011] The first laser and the second laser are turned on or off by independent switches, so that a single laser can emit a corresponding light beam;
[0012] It also includes a housing, wherein the housing has a first laser, a second laser, a transmission grating, a first lens, and a second lens built therein;
[0013] The shell is provided with avoidance notch grooves corresponding to the emission outlets of the six groups of parallel light beams. Each avoidance notch groove is covered with transparent glass. A flip cover is provided at the outer end of each transparent glass. When the flip cover is closed, the corresponding parallel light beams cannot be emitted. When the flip cover is opened, the corresponding parallel light beams are smoothly emitted, which enables the entire device to output parallel light beams at different intervals.
[0014] After adopting the structure of the utility model, the light beam emitted by the first laser is a light beam a, which is diffracted by the transmission grating into 0-order diffraction light, +1-order diffraction light and -1-order diffraction light, and the 0-order diffraction light, +1-order diffraction light and -1-order diffraction light are collimated by the first lens into light beam c, light beam d and light beam e; the light beam emitted by the second laser is a light beam b, which is diffracted by the transmission grating 3 into 0-order diffraction light, +1-order diffraction light and -1-order diffraction light, and the 0-order diffraction light, +1-order diffraction light and -1-order diffraction light are collimated by the second lens 5 into light beam f, light beam g and light beam h; light beam c, light beam d, light beam e, light beam f, light beam g and light beam h are emitted in parallel, realizing the six-laser beam emission function, and the emission of at most six groups of parallel laser beams can be completed by two groups of lasers, which reduces the cost and also reduces the power consumption.

[0020] The first laser 10 and the second laser 20 are the same lasers; the first lens 40 and the second lens 50 are the same lenses;
[0021] The transmission grating 30 is a long strip structure, including an incident surface 31 on one side and an exit surface 32 on the other side;
[0022] The first laser 10 and the second laser 20 are arranged at intervals along the long incident surface 31 of the transmission grating 30, respectively. The emitted light beams of the first laser 10 and the second laser 20 are arranged perpendicular to the incident surface 31. The two groups of emitted light beams are respectively diffracted by the transmission grating 30 and then emitted to form corresponding 0-order diffracted light, +1-order diffracted light and -1-order diffracted light. The first lens 40 and the second lens 50 are arranged at intervals along the long incident surface 32 of the transmission grating 30, respectively. The incident surface covers three groups of diffracted light formed by the first laser 10 diffracted by the transmission grating 30, the incident surface of the second lens 50 covers three groups of diffracted light formed by the second laser 20 diffracted by the transmission grating, the first lens 40 collimates the 0th order diffracted light, +1st order diffracted light and -1st order diffracted light corresponding to the first laser 10 and emits three groups of parallel light beams, the second lens 50 collimates the 0th order diffracted light, +1st order diffracted light and -1st order diffracted light corresponding to the second laser 20 and emits three groups of parallel light beams.
[0023] The first laser 10 and the second laser 20 are turned on or off by independent switches, so that a single laser can emit a corresponding light beam;
