Here we go! Tonight I got bored and FINALLY took some pics with $700 worth of low powered pointers! YAY!

I got some interesting results. My LLBR was running at 15mw like always, but the Aquarius was off peak; running average, 5-7mw. Still, on non fluorescent surfaces, the Aquarius was about 3x brighter than the LLBR. On a white fluorescent surface, they were very close in brightness and color.

Now, that being said, my interesting results is that my camera appears to be extremely sensitive to 405 compared to 473, because in nearly all of the pics, the 405 is dominant to the 473. I tried to take a pic of the fluorescence of the LLBR on my black emperor scorpion, Cuddles, but the LLBR was so bright to my camera it just wouldn't happen.

Anyhooo, on to what ya'll are here for.


The contenders-



On a fluorescent surface-



Non fluorescent surface (405 left, the 473 was much brighter in person)-



473 beamshot, clear air (it was slightly brighter than this shows)-



405 beamshot, clear air (looks about right)-



473 on non fluorescent white door-



405 same door-



473 on glass & chrome coffee table and tan non fluorescent carpet.



405 same thing-



Again, the 473 was brighter in every situation. I dunno why the camera saw the 405 so much better.



The judges were intrigued-


Aquarius modehopped here. 3mw if I'm lucky in that pic, they looked about the same in person.

So bottom line. If you need true blue, go it. But if you just want a fun laser, blu-ray is the most economical way to go :)

Thanks for the showdown :)

Re: SHOWDOWN!  473 versus 405!!

Nice comparison there. My cam is also exremely sensitive for 405. When I took a pic of my 100mw blu-ray and my 250mw red, whose beams looks pretty identical in brighness, but on my cam, the blu-ray looks crazily bright and blue, not purple! Why does this happen really? How come so many cameras don't like 405nm?

I love the way the dogs look at the dots in the last pic, it looks like they think "Hmmm. Which is the brightest one?" ;D

Your Blu Ray pointer has a led on indicator?

Re: SHOWDOWN!  473 versus 405!!

How come so many cameras don't like 405nm?
Camera's are not designed to handle or compensate for large amounts of near-uv light. The eye becomes insensitive quickly from 420 nm downwards, but the in the cameras color filters this transition is much more gradual. The same thing often applies at the infrared end.

For taking normal, everyday, photos this is no problem since nuv light is relatively scarse in nature, though UV filters exist for SLR's to filter it out entirely, aiding color rendition in outdoor photography.

Dashed lines is because the blue is pulsed. This means it switches on and off really fast. Normally it's so fast you can't tell, but if you wave it around it separates the breaks out and you can see the pulse effect :)

Cool side-to-side review :)

Did you buy the LLBR or did you DIY it? The LED indicator looks really cool.

I believe the quoted price in the CNI groupbuy (being run by scopeguy in the groupbuys section now, if you hurry you might be able to get in the current order, but I'm not sure), is something like $325 in the US. You can check that thread to make sure, just skip to the last 5 pages or so since that thread encompasses multiple buys. Also, for the 3 "Aquarius" pens received so far in that groupbuy, all 3 metered in the 12-15mW range even though we only paid for the 5mW model. Also great deals on the "Rigel".

(I put the names in quotations because technically that is the trademarked name from LaserGlow. The pens bought from CNI will be the exact same models, but since they're not from LG, they're not named with LG's trademark names).
