Abstract
The invention relates to a novel semiconductor green laser beam expansion device for teaching, which has the main technical characteristics that a semiconductor green laser light source is arranged in a plastic shell; the front end of the light source is provided with a round glass column; the plastic shell at the front end of the glass column is provided with a round hole; a switch control knob is arranged on the upper surface of the plastic shell; the switch control knob is over against a switch of the semiconductor green laser light source; a strong magnet is arranged in a magnet caulking groove on the lower surface of the plastic shell; by regulating the switch control knob, the semiconductor green laser light source emits green laser, and the green laser light is expanded by the round glass column at the front end of the light source and then is ejected through the hole at the front end of the glass column; and the plastic shell is adsorbed on a blackboard or other optical instruments by the strong magnet on the lower surface of the plastic shell. Due to strong green laser light and good teaching effect, the weakness of red laser is overcome. Moreover, the novel semiconductor green laser beam expansion device for teaching has simple structure, is convenient to use and is an ideal single-color teaching light source.
Description
The present invention relates to a kind of teaching with the green laser beam expanding device of novel semi-conductor.
At present, it is red laser that LASER Light Source is used in known teaching, and red laser beam weak strength, weak effect.
In order to overcome existing red laser beam weak strength, the problem of weak effect the present invention relates to a kind of teaching with the green laser beam expanding device of novel semi-conductor.
The technical solution adopted for the present invention to solve the technical problems is: the green LASER Light Source of semiconductor is installed in plastic casing; Front end at light source is installed a circular glass post; The circular glass post is vertical with the green LASER Light Source of semiconductor. on glass column front end plastic casing, open a circular hole; Circular hole and circular glass post, the green LASER Light Source of semiconductor are penetrated light-emitting window on same straight line; Laser beam is penetrated. a switch control handle is installed on plastic casing, is made the switch of switch control handle, below plastic casing, in the strong magnet caulking groove strong magnet is installed over against the green LASER Light Source of semiconductor.The by-pass cock control handle sends green laser by the green LASER Light Source of semiconductor like this, and green laser is penetrated by the perforate of glass column front end through at the circular glass post expansion bundle of light source front end by dress again.The magnet of below plastic casing, installing in the strong magnet caulking groove is adsorbed on plastic casing on blackboard or other optical instrument.
The invention has the beneficial effects as follows: because green laser beam intensity is strong, teaching efficiency is good, has overcome the weakness of red laser.The present invention is simple in structure, and is easy to use, and it is a kind of desirable monochrome teaching light source.
