10pcs lot Laser head 650nm 9mV 50mW Laser Cross Module Red Copper Head 5MW

If the laser head needs to be lit for a long time, please increase the current limiting resistance appropriately1. Never point the laser to yours or others' eyes at any time. Even if the laser is turned off, it may be turned on by mistake.2. The laser cannot irradiate any reflective surface or smooth surface. The laser has excellent reflectivity. It will reflect when irradiating the reflective surface. If it happens to irradiate people's eyes, it can ca injury.3. The laser is not a toy and should not be d by children, people with incomplete intelligence and people who do not understand the characteristics of the laser. In this case, it is very easy to ca injury.4. Wear speciaoles when using the laser, especially for invisible laser.5. The laser cannot shine on vehicles, and other manned vehicles.6. Pay attention to the safety of laser battery to prevent short-circuit combustion or battery explosion cad by others removing the battery.The particularity of laser emiion prince and generation proce determines that laser has the characteristics that ordinary light does not have: three good (good monochromaticity, good coherence and good directivity) and one high (high brightne).

Product Name:Laser small copper head (red light)nsmitting power: 5MWService life: more than 1000 hoursSpot mode: point spot, continuous outputLaser wavelength: 650nmPower: 50mwVoltage: 3VCurrent: < 20mAOperating temperature: - 36 ℃ ~ 65 ℃Storage temperature: - 36 ℃ ~ 65 ℃Spot size: 15m φ 10mm~ φ 15t is mainly d for laser toys, various levels, ground wire meters, etc. the laser head is composed of three parts: luminous tube core, condenser and copper adjustable sleeve. When sent to the r, these three parts have been aembled, the focal length has been adjusted, and has been d with strong . The r can work by connecting 3V DC power supply.

Theoretically, in the ideal case (no dust, no e, no obstacles), the nsmiion distance of laser is infinite. Under the condition of high air quality, when the laser head gives 20mA working current, the nsmiion distance can reach more than 1km. It can be clearly seen on objects 200 meters away at on cloudy nights; For closer distances, even in the daytime sun, it is clearly visible on outdoor roads and buildings.ing electronic pointer pen: when teachers give lectures, they laser points to remind students to observe and think.Electronic level ruler: let the motor drive the smooth head to rotate or twist and project it into a sight line on the wall for horizontal reference when decorating or posting new year tures.Micro LCD : remove the condenser and let the laser pa through the controllable LCD screen to produce a clear on the wall.Long distance laser : let the laser irradiate on the gla of the eavesdropping room, then receive the laser beam reflected from the gla, detect the ion of the gla and restore the sound of the room.e light controlled anti-theft alarm: install a laser emitting tube and photosensitive at one corner of the fish pond or watermelon field to be protected, and install a re mirror at the other three corners to form a protective area.Long distance laser wirele communication: a pair of laser nsceiver devices to face each other on the roof of two distant hos, and the serial communication protocol of single microcomputer to send and receive files and even connect to the Internet.
