Blue lasers are actually the same type of lasers that are used in Blu-ray technology. Although it is rarely prefered to the green and red ones, it could be used for what others do, which also reflects the individual unique aesthetic taste. As far as presentation pointers go, it can be a nice change of pace to use a blue laser pointer, but much more powerful blue lasers are also available. However it comes down to all other uses such as pinpointing something on the large screen or on the blackboard.
The laser was actually really bright. It's pretty cool to be able to see the actual beam. On a clear night, you could see the beam thousands of feet away. The kaleidoscope lens is cool, albeit a little gimmicky. The patterns are cool and both my kids and cats loved it. My only gripe is when you take of the kaleidoscope part, it makes the laser look incomplete. Wish it looked more flush when removed. Other than, that, super happy customer.
Very bright and shines extremely far. The only thing I was disappointed in was I had to order specialty batteries. I ordered rechargeable ones after.
It's ok, I got this perfect laser pointer, and the price is cheap. Thanks.
I got five laser pointers at a very affordable price during the activity. Absolutely good.
This is my first purchase for 5mw laser pen. I thought it not to be very bright at such a low output power. Actually, the light is much brighter than I expected, especially when it is used to pointing to the night sky.
Great laser. The laser point(where the laser hits the wall) is very bright, and can be seen for some distance if pointing at something. You can't see the beam in the daylight but at night it is visible. Great for pointing out stars. I bought a 5mW and a 50mW laser from htpow as well and this laser is my favorite. The 5mW is pitiful, the laser point is weak and blurry and the 50mW doesn't show a beam. All in all this is a great laser for a great price.
Blue Laser Pointers
Green Laser Pointers
Green laser pointers are now the world's most popular laser pointers, because the green light than red light 6 times more than red light beam significantly, while the price is much cheaper than the blue and yellow, green laser pointer is simply more powerful than red laser pen. Of course, this also means that green lasers are potentially more dangerous than red lasers. When operating this type of laser, it is important not to point it into anyone's eyes or to point it up in the sky towards any airplanes. It is probably not as much preferred lasers as an astronomy laser pointer, because brighter colors would make an object more visible in the sky.
Red Laser Pointers
Red laser pointers are by far the most popular and least expensive type of laser pointer. This is because the wavelength of the red color can be manufactured more easily than that of the other colors in the spectrum, red laser is also the only color that is available in the smallest size of laser pointers. Do remember that red laser light is powerful when it hits a certain object and converges into a point.
HTPOW Lasers are IR filtered for safety and the output power is measured on each unit individually for a 20-minute continuous period to ensure sustained performance. This high power laser test is done at least 3 times before the laser is shipped to the customer. All lasers are the best quality, the most competitive price. We guarantee all laser pointers products are free shipping, 30-days return policy, 1-year warranty period.
