Hello Skooter Blog readers. Today I talk about Laser 2 in 1 5mW 650nm Red + Verde 532nm 5mW (2 pilhas AAA) (2-in-1 5mW 650nm Red + 5mW 532nm Green Laser Pen (2*AAA)) acquired on DealExtreme, whose purchase has been detailed in last article here, so this article merely speak product.
The Laser 2 in 1 5mW 650nm Red + Verde 532nm 5mW AAA uses pilhas duas. It already comes with a pair of alkaline batteries brand Tianqiu, manufactured by Guangzhou Tianqiu Enterprise Co., Ltd., which also makes batteries brand Mitsubichi, then I think we are good batteries. Este laser is interesting, because it has two colors: red (with wave 650 nanometers in length) e verde (with wave 532 nanometers in length). Each emitter has declared power of 5mW. Are two buttons, each of which triggers a different color, and the two may be pressed simultaneously.
The construction of Laser 2 in 1 5mW 650nm Red + Verde 532nm 5mW é bem solid, its buttons work perfectly. The quality is the same as Green Laser 5mW 532nm with DX logo (2 pilhas AAA) and the 560nm Red Laser Pointer with 50mW - 2 pilhas AAA, both already featured here on Skooter Blog.
The Laser 2 in 1 5mW 650nm Red + Verde 532nm 5mW is also accompanied by a metal case, I think aluminum, perfect for transporting it safely in the bag. It came with a small dent, provalvelmente produced in transport, mas or laser Saiu ileso.
Although the two colors have, at least in the specification, the same power in the transmitter, o verde acaba ficando bem mais visível do que vermelho, what appears to be a characteristic of human vision, which is more sensitive to the wavelength of green, which is very close to the center of the visible spectrum, as we can see this figure from Wikipedia.
In short, I can say that this was a good purchase, the Laser 2 in 1 5mW 650nm Red + Verde 532nm 5mW is perfect for use in presentations, comes with a good kit to be stored, has two colors in the same device, and uses AAA pilhas, can be easily found on the market, including rechargeable version, so that the spent on “maintenance” laser can be greatly reduced as compared to models that use batteries less common.
As I always do in articles on lasers, I leave here also my warning “Do not be an asshole!”. Do not point the laser into the eyes of other people or animals; do not use your laser to disrupt sporting events, shows musicais, etc.; not the point to moving vehicles or aircraft. Several developed countries have banned or limited the maximum power lasers that can be imported. Let's collaborate so that the same does not happen in Brazil.
And I'm ending here the article on Laser 2 in 1 5mW 650nm Red + Verde 532nm 5mW (2 pilhas AAA) (2-in-1 5mW 650nm Red + 5mW 532nm Green Laser Pen (2*AAA)). If you also want to shop in DealExtreme, directly from Hong Kong, click here, good shopping.
