DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0015] Referring to FIGS. 2–3, the present invention includes: a positioning seat 20, having a first through hole 21 and a second through hole 22 inside, wherein the positioning seat 20 is combined with a front cap 23 and a rear cap 24, and the front cap 23 has a dust mirror 25; a first laser module 30, arrange a first tubular body 31 inside the first through hole 21 of the positioning seat 20, the first laser module 30 is provided with a first collimating lens 32 and a first wavelength laser diode 33 inside the first tubular body 31, for emitting laser light of first wavelength, wherein the first tubular body 31 has a first ball unit 311, the first through hole 21 has a first ball and socket unit 211 relative to the first ball unit 311, and a first fixing ring 34 is used to fix the first tubular body 31 to the first through hole 21; a second laser module 40, arrange a second tubular body 41 inside the second through hole 22 of the positioning seat 20, the second laser module 40 is provided with a second collimating lens 42 and a second wavelength laser diode 43 inside the second tubular body 41 for emitting laser light of second wavelength; the second tubular body 41 has a second ball unit 411, the second through hole 22 has a second ball and socket unit 221 relative to the second ball unit 411, and a second fixing ring 44 is used to fix the second tubular body 41 to the inside the second through hole 21; a first reflecting mirror 50, arranged on the positioning seat 20 obliquely with respect to the first laser module 30, and the inner surface of the first reflecting mirror 50 with respect to the first laser module 30 has a first wavelength laser light high-reflection coating 51; and a second reflecting mirror 60, arranged on the positioning seat 20 obliquely with respect to the second laser module 40 and the first reflecting mirror 50, and the outer surface of the second reflecting mirror 60 with respect to the second laser module 40 has a first wavelength laser light high-reflection coating 61 and a second wavelength laser light high-reflection coating 62.

[0016] With the feature disclosed above, after the laser light of the first wavelength passes through the reflection of the first reflecting mirror 50 and the second reflecting mirror 60, it coincides with the optical path of the laser light of the second wavelength which penetrating the second reflecting mirror 60.

[0017] Referring to FIGS. 3–4, when the first laser module 30 is a combination of invisible light (such as infrared light) and the second laser module 40 is a combination of visible light (such as green light); during nighttime use (with night vision goggles), only the first laser is turned on, the optical path of the first laser module 30 will be as shown in FIG. 3; during daytime use, only the second laser is turned on, the optical path of the f second laser module 40 will be as shown in FIG. 4, and there will not produce aiming deviation.

[0018] In addition, when the first laser module 30 is a combination of visible light (such as red light) and the second laser module 40 is a combination of visible light (such as green light); when only turns on the first laser module 30, the first visible light (such as red light) is emitted, when only turns on the second laser module 40, the second visible light (such as green light) is emitted, and when the first laser module 30 and the second laser module 40 are both turned on at the same time, the optical path will be as shown in FIG. 5. The optical paths emitted by the first visible light (such as red light) and the second visible light (such as green light) overlap and mix into the third visible light (such as yellow light), which can be used for achieving light blending effect.

[0019] Moreover, the corresponding first ball unit 311 and the first ball-and-socket unit 211 allow the first tubular body 31 of the first laser module 30 to adjust the optical path of the first wavelength laser diode 33 according to the first through hole 21, and then use the first fixing ring 34 to fix the first tubular body 31 in the first through hole 21; Similarly, the optical path of the second wavelength laser diode 43 can also be adjusted; After the optical path is adjusted, it can be ensured that after the first wavelength laser light is reflected by the first reflecting mirror 50 and the second reflecting mirror 60, it will coincide with the optical path of the second wavelength laser light penetrating the second reflecting mirror 60, which is convenient for the effect of light optical adjustment.
