Two tips for choosing a Laser pointer reasonably The powerful laser pointer is the most widely used laser light source, using the highest quality laser diode as the light source, the most accurate and focused reference plane projection. Due to the advancement of laser technology, laser lighting can now be combined with this design, making…

Fun cat and laser pointer game
Why are cats interested in laser pointers? Specifically, it uses the light spot generated by a handheld (it seems to have an automatic) laser device, and then moves the bright pattern generated by the laser. The light attracts cats and other instinctive animals (it is said that dogs don’t like it) in an irregular way…
Application of laser pointer
Laser is very suitable for pointing out branches, trees or other objects that must be cleaned and processed in the field of landscaping. Laser is much better than shouting. You have a tree line starting to encroach on the road, and some branches are dangerously approaching the local power line. As a property manager, you…
Why are laser Pointers so useful?
The laser characteristics 1.Laser radiation can cause genetic and physiological pest defects, male infertility or genetic mutations, and some agricultural pests continue to die after being irradiated by ruby and carbon dioxide lasers. Different species of insects have different sensitivity to different wavelengths of laser light. I found that different insects are sensitive to laser…
Why is the laser pointer a perfect tool?
Laser shows are entertainment activities using lasers. Usually, the light of one or more laser beams is affected by deflection too fast. Today, lasers can rise from less than 5 MW to 5000 MW or 5 MW, which means knowing where the combustion threshold is, which is usually at least 100 MW. This means that…
People know too little about the safety of laser pointers
Future buyers of lasers and lights ask us a legitimate question: is it safe to use Laser pointer? Is there a risk of using a laser? This article will tell you what your knowledge is about lasers and safety guidelines. The integration of laser pointer diodes in the device ensures a very strong diffusion of…
The laser pointer will not affect the body
As long as the temperature of objects in nature is higher than zero, they will continuously transfer heat in the form of electromagnetic waves, which is called “radiation”. The energy released by an object through radiation is called radiant energy. In other words, radiation is a process of releasing energy. Sunlight is radiation, but it…
Do you know the temperature of the laser pointer?
Laser products generally have an operating temperature range, usually between 0-40 degrees. The temperature is between 10-40 degrees. When the temperature of the laser pointer is too low, such as lower than the working temperature, the laser is not fully started and the light is very weak. With the increase of stability, the laser will…
The working principle and working method of laser pointer
The working principle of laser includes radio frequency control and receiver (USB interface). Driver installation is not required. The user can only control the receiver by clicking the corresponding RF key. In addition, the transmitter should not aim at a receiver that really reflects radio freedom. Principle of red laser rod. Because a laser diode…
Working circuit diagram of laser pointer
The Laser pointer is used for computer operation and can be positioned on the fluorescent screen of the display. When the light pen receives the scanning signal on the fluorescent screen, it converts the light pulse into an electric pulse, and the coordinate position of the light pen is calculated by the computer through the…
