Astronomical observations indicate that the star is perfect. At night, you can see blue light from hand to sky, so you can enjoy the constellation comments and the beautiful starry sky. Powerful blue laser pen is very good in terms of portability, often used for lighting, can also be used for academic presentations, seminars, research meetings, etc., these meetings are usually used for education and demonstration sites, very suitable for travelers. The red laser light is very bright in the dark, showing visible red and light spots.
It has the effect of ordinary green green laser pen shape, can switch to different star heads, each equipped with a 5 star head pattern, dazzling different patterns, new styles, patterns, etc. You can enhance the pattern, the diversification of entertainment, the following five stars, bird's nest, space and time tunnel, square, single point design rendering, the starry sky, green. A job romantic place, more fashion taste life, there is a image of the United States is called: one of the stars, one of the modern cities, such as meteor shower, fireflies best gift!Basically, unless something due to the fine particle scattering, such as air or crows repulsion laser cannot see its path (because it does not have spread to the nature of light itself), so in a vacuum or completely dry clean air inside the visible light range should be invisible to any color.
Every year, I made a mini planetarium at the cultural festival exhibition, but I was looking for a small laser pointer for cats because it was hard to see it as a guide when explaining it. Although I looked at it differently, the laser pen seemed to be heavily regulated, and I didn't know what to choose. Those familiar with laser pens, please advise! Don't exceed A 1mW. People with high output Pointers have an excuse, but if an accident happens, the eyes will be blind, which is a very close range. You won't get angry. You're under arrest. In addition, with your huge compensation, your life has been messed up.
When projection is about Q 1 m, do you have a crown laser pointer with a diameter of about 3 mm?Please keep the safety below 1 mW.Also, if you can change the size of the pointer diameter, it's even better.Myself is a safe, but I have a high power variable (indicates a variable diameter) focus, but it may be about 100 mw, but in the case of red, if maximization, tend to dull than expected.So if there is a problem with the request of the diameter of the 1 mw could change things, even bigger diameter may be dark, will not be seen (laughs) in addition, because I don't have any, I can say that although I think even something about 3 to 4000 yen in Japan, to some extent are separated, also can maintain a small point.
I also in most of the weapons, but it is understood that the enemy in the battle of 100mm laser pointer green is visible, I found the place where I can leave, so there are a lot of opportunities in waist circumference, in addition to shield pistol and a shotgun I delete it As you can see clearly, in the game, need a secret that tend to be unfavorable.The extent of laser scattering varies from wavelength to wavelength. Shorter wavelengths are more likely to be scattered by tiny particles in the air and water vapor, so they can be more clearly identified in green wavelengths that are shorter than red. Red does not scatter, which is hard to see, because there is hardly any. Obviously, if the wavelength is shorter, you should see it more clearly."Lasers can be spread and not spread over long distances, or they can converge to a very small place." This is the first feature of the laser. The laser features a dry length. Apollo USES a laser pointer to a large power super discount mirror for the lunar surface ranging why is it red?
Laser is used in retinal photocoagulation, usually in hospital. Retinal photocoagulation is designed to eliminate the lack of oxygen in the retina, to prevent new blood vessels, or to reduce new blood vessels. Photocoagulation will sacrifice some normal retinas, but it will inevitably prevent all the retinas from becoming tangled. This treatment is likely to lead to this type of misunderstanding, which is to prevent the deterioration of retinopathy, rather than to restore the original state of treatment. In rare cases, vision may go up due to the whole retinal swelling, but in many cases, the visual acuity of the treatment is either constant or quite low. According to the progress of retinopathy, the number of burn laser pointer irradiation and the range of exposure will be different. Retinal photocoagulation is very effective in early stage and is an important method for future prevention of blindness.
