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.
This was a birthday gift for our Grandson and he loved it.
These Are Awesome, They Are worth Every Penny! I didn’t Think Twice When I Ordered These, They Were Delievered To My Door In Just 2 or 3 Days and Everything Is Very Solid.
As another reviewer pointed out the dual cone effect is not visible in the red and violet laser without a significant amount of smoke. This is a limitation of the light wavelength and you would basically need to use this in a building fire to see look like the product shots. The dual green works much better with less smoke needed.
Although a very good design and maybe a perfectly good product for many, I am overall pleased with the unit as the lasers are 5mw (both) and the desired color (red is a standard color red and purple is also) but I have to say that the picture/photo in the product's description is not a true likeness of the product's output.
Neat and Unique toy - Cats LOVE it
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.
