1. Pay attention to the safety of the laser battery to prevent others from dismantling the battery and causing short circuit combustion or battery explosion accidents.
The emission principle and production process of laser determine that laser has characteristics that ordinary light does not have: three good (good monochromaticity, good coherence, good directionality) and one high (high brightness).
3. Mainly used for laser toys, various level gauges, ground wire gauges, etc
Creating an electronic teaching whip pen: During a teacher's lecture, a laser projection point is used to prompt students to observe and think.
4. Electronic level ruler: Use a motor to drive the bald head to rotate or twist, and project it into a straight line on the wall for horizontal reference during decoration or posting of New Year's paintings.
5. Micro LCD projection: Remove the spotlight and allow the laser to pass through a controllable LCD screen, which can produce clear projections on the wall.
6. Remote laser monitor: Let the laser shine on the glass of the room being eavesdropped on, then receive the laser beam reflected back from the glass, detect the vibration of the glass, and restore the sound of the room.
7. Remote light controlled anti-theft alarm: Install laser emitting tubes and photoresistors in one corner of the fish pond or watermelon field that needs protection, and install reverse mirrors in the other three corners to form a protective zone.
8. Long distance laser wireless communication: Using a pair of laser transceiver devices facing each other on two distant rooftops, the serial communication protocol of the microcontroller can be used to send and receive files, and even connect to the internet.
This laser head consists of three parts: the light-emitting tube core, the condenser lens, and the copper adjustable sleeve. When it is sent to the user, these three parts have been assembled, the lens focal length has been adjusted, and it has been glued with strong glue. The user can connect the 5V/3V DC power supply to start working.
matters needing attention:
This component is sensitive to static electricity. Without proper anti-static measures, do not directly touch the laser tube body with your hands. In addition, this product must have a qualified driving circuit to work properly. The voltage is the same for different powers, but the working current is different. The driving current of the circuit to the tube needs to be controlled within a safe range, otherwise it will affect the service life.

9MM-3V

Product description:
lfyou need to light up the laser head for a long time, pleaseincrease the current limiting resistor appropriately.
1.The laser can not be pointed at oneself or others' eyes atany time Even when the laser is turned off, there is apossibility of turning on by mistake.
2.The laser can not irradiate any reflective surface orsmooth surface, the laser The light reflectivity is very good, itwill reflect when irradiated on the reflective surface lf it hitshuman eyes, it can cause injury.
3.The laser is not a toy.Don’ t give children who don’tunderstand the characteristics of the laser People use it,because in this case,it is easy to cause injury.
4.Wear special goggles when usinglasers. For invisible lasersThis is particularly important.
5.Lasers cannot be irradiated on vehicles, airplanes andother transportation vehicles with people.6. Pay attention to the safety of the laser battery to preventothers from disassembling the battery to cause short Roadburning or battery explosion accident.

Product dpplications:
Mainly used for laser toys, various levels, groundinginstruments, etc., this laser The head consists of a light-emitting tube core, a condenserlens,and a copperadjustable sleeve.When given to the user, these three partshave been assembled, and the lens focal length is also highspeed,And it has been glued with strong glue, and the usercan connect to the 3V DC power supply Make.Theoretically,underideal conditions (no dust, no smoke, noobstructions)The transmission distance of the laser isunlimited.The laser head is in high air quality Under thecircumstances, when the working current is 20MA, thetransmission distance can reach lKM Above, on a generallycloudynight,randomlyilluminate objects 200 meters awayCan be clearly seen,for closer distances, even in the daytimesun,lt is also clearly visible on outdoor roads and buildings.

Note:【Warning】Laseris harmful to human eyes, please donot aim directly at human eyes, please stay away Storechildren to avoid accidental injury, such as caused by improperuseAll consequences ofsuccess are borne by theuser.

4.5V

Composition of the product:
Laser head by the light-emitting tube core, focusing lens, sleeve of three parts When sent to the user, these three parts have been assembled, the lens focal length is also adjusted and has been glued with strong glue, the user can work by connecting the 4.5V DC power supply.

Product Description:
Under ideal conditions (no dust, no smoke, no obstructions), the transmission distance of the laser is unlimited. This laser head in the case of high air quality to the 20MA working current, the transmission distance can reach more than 1KM, in general cloudy night, casually irradiated to 500 meters away from the object is clearly visible; for a closer distance, even in the daytime under the sun, shining in the outdoor pavement, buildings are also clearly visible!

Working voltage:
4.5 volts 51 resistance Working time: quite long (because there is no accurate test)


Caution:

This component is sensitive to static electricity, without good anti-static measures, please do not use your hands to directly contact the laser tube body, in addition, this product must have a qualified driving circuit to work properly, different power voltage is the same, but the working current is different, the circuit of the tube drive current needs to be controlled within a safe range, otherwise it will affect the life.
