1.  How do I know that I am purchasing a genuine Atlasnova laser pointers?

To make sure that you are buying a genuine Atlasnova laser pointers and not a counterfeit Atlasnova laser pointers, always insist on seeing the FDA sticker before purchasing any laser pointer. Our pointers have our company's name and address on each FDA sticker. And our laser pointers were manufactured from Taiwan and NOT in China!  

2.  My pointer's FDA sticker says it was manufactured in 2007.  Will this mean my pointer is an old stock, considering it is already 2008?

Absolutely not.  Since we order 1000 pieces a time, our manufacturer prints the danger sticker in batches of thousands at a time.  Even if we ordered in early part of 2008, and if our manufacturer still have 2007 stickers, they will use those stickers.  Rest assured that your pointer is brand new.

3.  What is the difference between 635nm and 650nm?

    - They are identical including a high quality collimating lens except that the 635nm wavelength appears brighter to the human eye than the 650nm wavelength. The 635nm laser diodes are hard to produce and are seldom available. They are especially sought after by collectors and those instructors who teach in an environment of high ambient light.

4.  You say that the lasers are true 5mW but the specifications rate the lasers between 1-5mW.  How do you guarantee 5mW?  I will be using the laser for diffraction pattern experiments at college and will be able to ascertain the wavelength then.  Have you conducted any such test yourself?  I'm only curious because I already own a similar laser that's rated between 3-5mW and it comes around 3.4mW.  I am interested in buying a 5mW laser but I would like some reassurance?

5.  What's the difference between the APC and non-APC green lasers?

6.  Can the whole beam be seen?

     - If it is very dark the beam can be seen.  These are the most visible pointers you can buy but they are not "light sabers".  See attached picture sent by a customer showing the beam from a green laser pointer.

Green Laser Beam

7.  Do you think red laser will be visible at 50 feet in bright sunlight aimed against a stucco wall?

    -  No. If this is a requirement, I think you need to consider green laser pointers.

8.   I was wondering for the laser pointer ... in the dark, do you only see a dot or do you see a beam?

     -  It has to be very dark or some smoke added - this goes for all of them.  Please see attached picture sent by a customer showing the dot. For the beam, see question #3.  Green Laser Dot

9.   If I use green laser pointer in the dark, will the beam itself be visible to the naked eye?
     -   It must be quite dark.  This model is very popular with astronomy people, they are very happy with it.

10.   Is the range of green laser pointer roughly 15,000 ft then ? if outdoors in darkness with few clouds?

       - Talking about range for these devices is pretty useless.  A seller can say any "range" they want.   It will be much farther than you will be able to see.  What is important is the quality of the optics.  Our pointers are superior in this regard. 

11.  How long will the green laser pointer work without having to change the batteries?      -  Our green laser pointers are very efficient.  A set of batteries will last at least 3 hours.  This is pretty good for a powerful green pointer.

12.  Could you give me safety information on laser pointers?
