10mW Blue Violet Laser Presentation Pointer
10mW Blue Violet Laser Presentation Pointer
Blue lasers are on the cutting edge of consumer laser pointers. This beautiful blue-violet laser is more pleasing to look at than red or green!
Please note, because the human eye is more sensitive to green than to blue, this laser pointer will appear less bright than a similar green one. However, the milliwatt output is factory-calibrated and accurate. In daylight or bright places, the blue laser will be more difficult to see. In darkness, it is still bright and perfect for use in presentations. In fact, it is not “too bright” to look at like some green lasers!
User Ratings and Reviews
4 Stars Not terribly bright, but a decent violet laser for the price!
As a previous reviewer mentioned, this laser was a little disappointing when first turned on. This pointer produces a spot which is dimmer than a class II (<1 mW) red laser pointer when shone on a white wall in a dark room from 45 feet away. The decreased sensitivity of the human eye to this wavelength is somewhat misleading though. You begin to appreciate this more if you shine it on something which will fluoresce. Flurorescent yellows, greens, orange, etc yield amazingly bright spots. Glow in the dark objects are quite responsive as well.
The buyer must understand this is not going to be a cool presentation pointer. The spot is simply too dim to be useful in anything but the darkest room with very dark slides.
In the end, it’s a decent price for a compact violet laser, so long as your expectations are realistic.
1 Stars Ordered two separate times & they sent Green laser instead
I ordered this item twice. Each time they sent a box, labeled as a blue/violet 10mW laser, but inside was a 50mW green laser. Sent both back. Distributor is got things messed up.
4 Stars blue-violet laser
When I first received this in the mail, I was a bit let down.
Against a white wall it’s not nearly as bright as the green 5mW pointer, but if you shine it at an object that has phosphorus, or other fluorescence chemicals in it, it’ll glow a bright blue.
Since it’s a UV emitter, it works like a black light on day-glow objects. It’s in the UV-A range, which isn’t as harmful as UV-B radiation.
An InGaN laser emits 405 nm directly without a frequency doubler such as the 473nm blue and 532nm green lasers, which means that accidental dangerous infrared emission is impossible.
Don’t shine it at “Transitions” eyeglasses, it’ll leave a mark that lasts for about an hour or two.
Overall, it’s worth the price.
