A laser pointer is a small device that emits light beam used to highlight different objects in a presentation. This tool has been used to replace the usual stick or extendable metal rods that are being used to point at objects. All titanium laser pointers are much advantageous when it comes to effortlessly pointing at object that is too high or too far. The beam of the laser can point to anywhere unlike the stick or rod which has a limited reach.Laser pointers use the laser technology where a light is amplified using battery power. At present, laser pointer batteries are rechargeable like CR123 or 18650 battery. The lights of pointers’ laser available today are 473nm, 405nm, 650nm, 980nm,1064nm,808nm and the most common 532nm green beam. Now, green laser pointer is the widely used color of laser because of its high visibility where you can clearly see the light of the beam being produced. Compared to the yellow light which may diffuse, green light can be more stable when it comes to temperature and background light. Green laser pointer has a high frequency having the wavelength of up to 532nm that is powerful enough to become very visible. Other high frequency laser beams available in the market today are violet and blue. You can still find red or red-orange beams that is more powerful that its ancestors.
When choosing a laser pointer, you can look at different strengths and according to the need. These laser pointers beams can be hazardous to the eye but the good news is that most of the product designs of laser pointer today are created with safety features. If you want something that you can use as light or just a toy then you can choose the 532nm 150mw titanium green laser pointer. But if you want something that you can use in parties, you can have the powerful lasers such as green, red, blue, and violet. But be responsible in using it because pointing it to the eye of person may cause blindness or eye defect. Moreover, the eye injury caused by laser irradiation is cumulative, so even the little injury is not obvious enough, but don't wait until it's too late. You must wear the laser safety goggles when operate these lasers and encounter these lasers beams.
