Laser Pointer

The Invisible Scam of Green Laser Pointer You May Encounter
When the world is totally shocked by the super emerald power of green laser pointer and swarm into the rare laser websites, they never think that they would pay dearly for this passion. I’m one of the victims who had sacrificed the hard-earned money for the not-userly-friendly laser beam.
I've personally had 5 lasers from those popular websites where you could nearly find the laser of any output power with the weird mummy names. So I feel obliged to tell a piece of truth about these green lasers and their sellers, coz bad news is bound to spread fast. All but the 200mw green laser pointer have not been performing to specs. I wonder why these lasers are made to be underpowered and those sneaky laser retailers really underrates the non-fishy mind of we laser lovers. Even if we are never able to do any research upon their specs in time.
You’ve got to be careful about those low-end lasers. I mean not only about the low price. Some laser sites sell lasers at pretty competitive price, but they tend to guarantee the long life expectancy of portable lasers, while some manufacturers tend to cut corners and some probably are missing their IR filter. Most laser lovers have been misled by the fuss about the IR filters made by the wicked lasers. I learnt that in some sense, optical brightness may be dimmed by the multiple wavelengths within the single laser beam. I later checked that one of my green lasers was putting out green at 532nm, but there is also very few infrared, at 808nm and/or 1064nm.But if one plans to buy a below 100mw green laser, you don’t have to be bothered by the IR filters, coz it influences little the power and brightness of a lower powered laser. So it has little to do with the effective cost of the product. Sometimes the module or design costs much more.
A good example is LaserPointerPen.Net company which tend to add IR filters to all green laser pens while those below also has a super high cost performance. Due to its limited stock that only covers three most upgraded laser series, its laser products obviously becomes the most competitive especially for those professionals. The self-appointed No.1 laser site wickedlasers spare no efforts to hire some orators to spread the life-and-death importance of the IR filter for any laser use, and god knows the mere reason is that they’re profiting big upon those cheap IR filters. Few pros deny admit this seeming-‘white’ lie.
I’m a laser lover and trying not to be biased against any laser manufacturers or retailers. Why I don't like wickedlasers is that they don't send the verified output of each laser they sell. Most reputable laser companies do this and their's are GUARANTEED over-spec, every single one.

Trixie Laser Pointer - Laser pointer $3.49 This nifty hi-tech Trixie toy should keep your cat happy for hours chasing the dancing red laser dot wherever it twists and turns. The ultimate playful experience! Colour of item may differ from displayed illustration. Note for correct use of the Trixie Laser Pointer Playing for long periods of time with an intangible toy does not make for long-lasting fun. To avoid any frustration the FroliCat Bolt Laser Cat Toy should not be left running for such long periods of time. Treats or an extra physical toy (e.g. a dangler pole toy ball or mouse toy) should be provided now and then. This will increase your kitty´s chance of success and ensure a more enjoyable experience chasing after the little red dot. Warning Avoid pointing the laser light towards eyes as this can cause permanent damage. Hazard class level 2 The accessible laser radiation is only within the visible spectrum range [400 nm - 700 nm]. Brief exposure (up to 0.25 sec) is not harmful to the eyes. 3 Batteries included What´s this? |

Green Laser Pointer II $69.99 Okay, just about everyone has a red laser pointer. Heck, we even sell a fine one here at ThinkGeek. But, we're pretty sure you want to be a superior geek - and doing it with a green laser is the way to go. This pointer is significantly brighter (about 50 times) than a red laser pointer and because of its unusual color it is much more noticeable. I mean come on, a 532 nm green laser wavelength is obviously superior to a laughable 650 nm red laser wavelength. And unlike a red laser, the green beam itself can be seen in mid-air in dark conditions, not just the laser beam dot. This allows the green laser pointer to be used for pointing to star constellations (skypointing) and also just generally look cool as hell. The green laser beam dot can be seen at much greater distances than with a red laser pointer. Since green direct injection laser diodes aren't readily available, this pointer is based on the use of Diode Pumped Solid State Frequency Doubled (DPSSFD) laser technology. A high power IR laser diode at 808 nm pumps a tiny block of Nd:YVO4 generating light at 1,064 nm which feeds a KTP intracavity frequency doubler crystal to produce the green beam at 532 nm. Features of this unit include: Very bright green laser at 532 nm wavelength Output power of Range of approximately 9,000 ft (2600 m) in darkness 1.1 mm beam diameter at source Momentary push button switch Solid, heavy duty construction Constant wave output (as opposed to pulse output) Takes 2 "AAA" batteries (not included) Can be used for skypointing, projection on low clouds, signaling, highlighting potential explosives Dimensions: 5.6" x .5" dia 90-day warranty Available in Black or Silver color Interested in quantity discounts or custom logo imprinting? More info here. Warning: Green lasers are very powerful. Pointing at aircraft may land you in jail. Without a Monopoly card to get you back out. Use it wisely. |
