If you need to keep the laser head lit for a long time, please increase the current limiting resistor appropriately
1,Never point the laser at yourself or someone else's eyes at any time,Even when the laser is turned off, there is a possibility of accidental activation.
2,Lasers cannot be used to illuminate any reflective or smooth surfaces,The laser has excellent reflectivity,When irradiated to a reflective surface, it produces reflection,If it happens to hit someone's eyes,Can Cause Harm.
3,Lasers are not toys,Not for Kidsren,Intellectual Disability,For those who do not understand the characteristics of lasers,In
This Case,Very Easy to Cause Harm.
4,Wear special goggles when using the laser device,For invisible laser,This Point Is Especially Important.
5,Lasers cannot be directed at vehicles,Aircraft and other means of transportation with passengers.
6,Please pay attention to the safety of the laser device battery,Prevent others from disassembling the battery to cause short circuit, combustion, or battery explosion accidents.
The special nature of laser emission principles and production processes determines that lasers have characteristics not found in ordinary light:That Is, Three Good Things(Good Monochromaticity,Good Correlation,Good Directionality)One High(High brightness).

Mainly used for laser toys,Various Levels,Ground Wire Meter, Etc,This laser head is composed of a light-emitting tube
core,Concentrating Lens,Copper Adjustable Socket Three Parts Composition,When Sent to the User,These three parts have already been assembled,The lens focal length has also been adjusted properly,And it has been glued with strong adhesiveGood,User Connection3VDirect current power supply is sufficient for operation.
Theoretically,In the Ideal Case(Dust-free,No Smoke,Without Any Obstacles),The transmission distance of laser is unlimited.Thislaser head operates under high air quality conditions,For20MAWhen the Working Current Is,The Transmission Distance Can Reach1KMAbove,On a typical cloudy night,Casually shining upon200Objects beyond meters are clearly visible;For close proximity,Even under the sun during the day,Lighting the outdoor pavement,It is also clearly visible on the building.
Making an Electronic Pointer Pen:When the Teacher Is Lecturing,Use laser projection points to encourage students to observe and think.
Electronic Level:Let the motor drive the bald head to rotate or twist,Projected into a straight line on the wall,For reference
when decorating or posting New Year pictures.
Micro Lcd Projection:Removal of the Condenser,Let the laser pass through the controllable LCD screen,Can produce clear projections on walls.
Long Distance Laser Monitor:Let the laser shine on the glass of the room being eavesdropped on,Then receive the laser beam reflected back by the glass,Detects glass vibrations and restores room floor sound.
Remote Light-Controlled Anti-Theft Alarm:Install a laser emitter and photoresistor in a corner of the fish pond or watermelon field that needs protection,Install reverse mirrors at the other three corners,This forms a protective zone.
Long-distance Laser Wireless Communication:Use a pair of laser transceivers to point at each other from opposite ends of two distant rooftops,Use the serial communication protocol of the single-chip microcontroller to send and receive files,Even Networking.
