Use
The specificity of the laser emission principle and the production process determines that the laser has the characteristics that ordinary light does not have: three good (good monochromaticity, good coherence, good directivity) and high (high brightness). Using the laser’s good directionality and high brightness, it can be widely used in health care, military, counterfeiting, security, stage (red, green, and blue) lights, various electric tools, measurement classes, instruments, equipment, spirit levels, positioning Meter, rangefinder, thermometer, laser marking
Instrument (line throwing instrument), various sheet cutting and forming machines, stone machinery, woodworking machinery, metal sawing machines, packaging machinery, knife setting, threading, clothing (sewing machines, cutting machines, automatic manual cutting machines, bag openers, Bar tacking machine, cloth drawing machine, embroidery machine, printing machine, beading machine, button sewing machine, riveting machine, beer machine), electronic measuring tools, mouse, USB flash drive, camera, mobile phone, projection teaching flip pen, laser pointer , Handicrafts, indoor and outdoor decoration, flashlights, gifts,
Toys and other products. Convenient and fast, intuitive and practical, easy to install, stable and reliable. Can greatly improve work efficiency.
Precautions
①This component is sensitive to static electricity. Please do not directly touch the laser tube body with your hands without anti-static measures.
②This product must have a qualified drive circuit to work normally, the voltage of different power is the same,
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 life.
Laser diode operating instructions
1. Question: What is the normal working voltage of the laser diode? What is the current?
Answer: Since the laser is a polar diode, the polarity cannot be reversed, and the supply voltage is constant DC (voltage and current are different for different tubes)
2. Question: How to avoid human body contact and electrostatic objects contacting the laser tube, so as not to burn the laser tube?
Answer: You can put a rubber sleeve on the periphery of the laser tube or use electrical tape to insulate it.
3.Q: Is the laser tube sensitive to temperature? What problems should be paid attention to when welding?
Answer: The laser emitting tube will decrease the luminous efficiency or even not work as the temperature rises;
① Generally, a single welding can not exceed 2 seconds to avoid welding overheating and overheating for a long time.
②One more point: You can't bare your feet when welding! Because the ground is conductive, students who don't believe it can try to touch the 5V power supply with bare feet (5V power supply is absolutely safe)
4.Q: What are the more scientific methods for welding laser heads?
Answer: The laser head has three pins, one of which is a fixed pin; when soldering, the fixed pin is not soldered first, and the other two pins are soldered first (note the positive and negative)
5. Vertical divergence angle θ⊥: the angle at which the light-emitting band of the laser diode opens in the vertical PN junction direction, generally around 15°C~40°C.
6. Horizontal divergence angle θII: The angle at which the light-emitting band of the laser diode is opened in the direction parallel to the PN junction, generally around 6°C~10°C.
