Take a look,

In the picture of the top of the laser, does that look like an IR filter?

They look pretty small and compact, kinda neat for the keychain

I'm not sure that it does have an IR filter but from the look of the photo reflecting the light it may well have one...

If I got my info correct this does not have an IR filter. This style was my first laser that got me into greens and now reds and in the future blue's, I got mine off Ebay. Back to the subject I ran it through my Laser check the other day as I found it again (the laser) and my 10mW on its original CR2 battery was measuring over 55mW (can't remembr exactly) and believe me that aint all Green, I dont have any IR filter's to test it's true output.

Its a nice design and its small and handy but I wouldnt trust the 50mW to be 50mW of pure green.

nope, the DX pen lasers are not ir filtered. when i got my 30, i opened up my 20 and all there was was the pump diode, the crystal and the beamsplitter and lenses.

Things - this has been discussed many, many times, I have personally disected one, and so has Psuedo - we have run tests by adding another IR filter inbetween the lasers and the power meter, and have discovered that they infact do have IR filters - all the pen types 50mw and below have good IR filters, as a matter of fact, and the 100 and 200mw versions have IR filters like swiss cheese ! I believe you missed the IR filter - or yours may be one out of a LOT of them that does not - but I owuld tend to think that it does, and you might have missed it. No offense intended of course.
