Abstract
The utility model provides a reflective telescopic sight. The reflective telescopic sight comprises a light emitting element used for generating a light source, and a light dividing lens used for reflecting emergent light of the light emitting element to parallel light. The reflective telescopic sight is characterized in that the light emitting element is a semiconductor laser, laser beams generated by the laser are thinner than light beams generated by a light emitting diode (LED), and a light spot projected by the laser beams is small, so a target will not be covered in an aiming process, and the reflective telescopic sight is favorable for observing the aiming target clearly and high in accuracy. Moreover, an aspherical lens is used as the light dividing lens, and thus the reflective telescopic sight is small in parallax and also favorable for promotion of aiming accuracy.

Summary of the invention
The purpose of this utility model is to overcome existing reflex sight to adopt LED that most that light source causes hiding in the aiming process target or target is provided, and causes pointing accuracy low, even the problem that can't shoot.
For achieving the above object, the utility model provides a kind of reflex sight, comprise in order to the light-emitting component that produces light source with in order to the emergent light with this light-emitting component being reflected into the beam divider of directional light, its special character is that described light-emitting component is semiconductor laser.
Above-mentioned reflex sight, comprise that also being arranged on described semiconductor laser goes out the pupil place in order to eliminate the light hurdle of veiling glare, it is provided with semiconductor laser and goes out the coaxial micropore of pupil, incides on the described beam divider after the laser of semiconductor laser emission passes this micropore.
Above-mentioned beam divider is non-spherical lens.
Above-mentioned non-spherical lens is the tire tread lens.
Above-mentioned tire tread lens cross section is circular.
Above-mentioned reflex sight, also comprise in order to driving the drive circuit for laser of described semiconductor laser, this drive circuit for laser comprise the permanent power driving circuit of laser instrument, modulation semiconductor green (light) laser output pulse width so that the average optical output power of described semiconductor laser reach setting luminous power pulse width modulator and be used for giving the permanent power driving circuit of described laser instrument and pulse width modulator that the voltage-stabilized power supply of power supply is provided.
Above-mentioned semiconductor laser is that wavelength is between the semiconductor laser of 400nm～980nm.
The reflex sight that the utility model provides adopts semiconductor laser as the light-emitting component that light source is provided, it is thin that the light beam that the laser rays beam ratio LED of its generation produces is wanted, the hot spot of projection is little, can in the aiming process, not cause blocking target, be beneficial to and observe run-home clearly, precision is higher.And adopt non-spherical lens as beam divider, its parallax is less, also is conducive to the raising of pointing accuracy.
