This is my Wicked Lasers Spyder 3 Arctic G2 445nm 1W Blue Diode Laser
with the Beam Expander affixed to it.

The Beam Expander is a nifty little gadget that screws onto the end of your S3 Spyder Arctic G2 445nm Blue Laser (any vintage), Krypton, or any other Spyder III series laser that expands the laser's beam by 10x.

This at first may appear to be counterproductive, but in this case, looks really ***ARE*** deceiving.

What the beam expander does is increase the laser's range by reducing the beam divergence (a value usually expressed in milliradians or mrad) by ten times; this allows the laser's beam to stay narrower, longer.

SIZE

To use your spiffy new (or corroded old

) Beam Expander, unscrew & remove the current optic or lens from your Arctic, Krypton, or any other Spyder III series laser, and screw the Beam Expander on...yes, it's really that easy.

Adjust the focus by turning the knurled (texturised) ring near the base of the Beam Expander.

There are no batteries to fuss with, so I don't have to tell you which part to remove, kick under the kitchen sink crawling with rats and cockroaches with full bladders, and then tell you rather emphatically not to.

This is an accesory that screws onto your Arctic 445nm blue laser, not a flashlight. So I won't try to drown it in the toliet tank, bash it against a steel rod or against the concrete floor of a front porch in effort to try and expose the bare Metalmarineangemon - er - the bare Metaltrailmon - um that's not it either...the bare Metalsusanoomon...er...uh...wait a sec here...THE BARE METAL (guess I've been watching too much Digimon again!

- now I'm just making {vulgar term for feces} up!!!), let my mother's big dog's ghost or my sister's kitty cats spring a leak (uranate) on it, hose it down with a gun, run over it with a 450lb Celebrity motorised wheelchair, stomp on it, use a medium ball peen hammer in order to bash it open to check it for candiosity, fire it from the cannoñata, drop it down the top of Mt. Erupto (I guess I've been watching the TV program "Viva Piñata" too much again

- candiosity is usually checked with a laser-type device on a platform with a large readout (located at Piñata Central {aka. "Party Central"}), with a handheld wand that Langston Lickatoad uses, or with a pack-of-cards-sized device that Fergy Fudgehog uses; the cannoñata (also located at Piñata Central) is only used to shoot piñatas to piñata parties away from picturesque Piñata Island, and Mt. Erupto is an active volcano on Piñata Island), send it to the Daystrom Institute for additional analysis, or perform other indecencies on it that a flashlight might have to have performed on it. Therefore, this section of the Beam Expander's web page will seem a bit more bare than this section of the web page on a page about a flashlight.

The albedo of this structure is ~15.

You can see in the beam itself that it starts out significantly wider as it exits the laser.

The Beam Expander vignettes (cuts off) the Krypton's beam by ~55%, which is why the beam appears "flared out".
This is a fault of the Krypton laser itself, not the beam expander; the beam appears to emerge from the Krypton slightly off-center.

TEST NOTES:
Test unit was sent by Jeice of Wicked Lasers on 05-06-13 (or "2013 06 May" if you prefer), and was received on 05-16-13 (or "2013 16 May" if you prefer). However, it was defective so a replacement was sent at once -- the replacement was received at 11:12am PDT on 06-03-13.

UPDATE: 06-14-13
I measured the beam diameter at aperture both with and without the Beam Expander in place.
They are as follows:

(Arctic; no beam expander):
2.0mm fast axis
5.50mm slow axis)

(Arctic; beam expander in place):
4mm fast axis
30mm slow axis

(Krypton; no beam expander):
2.0mm

(Krypton; beam expander in place):
28mm*

* Beam is being vignetted; beam diameter at aperture may be a bit innacurate as a result.
The following photograph shows this:

PROS:
Very cool accessory for your Spyder III laser
Increases the laser's visible range
Nice looking -- especially when affixed to your Spyder III laser

NEUTRAL:

CONS:
Beam must emerge from the laser perfectly centered

I'm uncertain just how I should rate this product, as I do not have access to a laser test facility with significantly longer range than what I currently have (~275 feet {~83.8M}}
