Arctic 445nm LaserShades (2), retail $29.99 (www.wickedlasers.com...)
Manufactured by Wicked Lasers (www.wickedlasers.com)
Last updated 10-06-10



This product does not emit light of its own, so the standard review format will not be used; however, since I consider them "test equipment", they will be furnished with a "star" rating. This web page will consist of just some informational text, four photographs, and three spectrographic analyses.




These are laser safety goggles designed for the blue (~445nm) diode laser -- they were actually made specifically to be used with the Wicked Lasers Spyder 3 Arctic 445nm 1W Blue Diode Laser.

They have acrylic lenses, a plastic frame, and a pair of temples (stems) like regular eyeglasses so that they don't just fall off.


SIZE





This is what these Lasershades look like when being used.


Blue laser spot from the Wicked Lasers Spyder 3 Arctic 445nm 1W Blue Diode Laser (2) {on maximum power} as viewed through these glasses.
=442.00nm



Spectrographic analysis of daylight to use as a control.



Spectrographic analysis of daylight with these glasses placed in front of the spectrometer's light input aperture.
Note the sharp decrease in transmission below ~550nm.



Spectrographic analysis of the Wicked Lasers Spyder 3 Arctic 445nm 1W Blue Diode Laser (2) with these glasses placed in front of the spectrometer's light input aperture.
That broadband "hump" peaking at ~610nm is fluorescence from the lenses of the glasses themselves.





Video on YourTube showing how well these LaserShades block the laser radiation from the S3 Spyder Arctic 445nm Blue Laser (2) that they were furnished with.

This clip is approximately 5.555567345823 megabytes (5,722,960 bytes) in length; dial-up users please be aware.
It will take no less than twenty eight minutes to load at 48.0Kbps.




Now for the good part: POWER MEASUREMENTS!!!

With these LaserShades in place, power output of the Wicked Lasers Spyder 3 Arctic 445nm 1W Blue Diode Laser (2)was measured at:

15.60µW (MICROwatts!) {low}
42.90µW {high}.

I believe that all of the power (yes, ALL of it!) is from fluorecence of the lenses themselves!!!



Does this evaluation look an awful lot like the one I made for this product?
Thought you'd say so.
That's because they're the same product, but this newer model attenuates laser radiation at the designed wavelength so much better!!!







TEST NOTES:
Test unit was furnished with the S3 Spyder Arctic 445nm Blue Laser (2) that I received from D.K. on the US east coast (sent to him by www.wickedlasers.com) on 12-03-10 (or "03 Dec 2010" if you prefer).

The primary reason that this product received 4.5 stars and not 5 is because they offer no protection against laser radiation coming in from the sides, top, or bottom. Their ability to attenuate laser radiation at their design wavelength however, is absolutely stellar!!!

Interesting.

It seems WL have changed the glasses from the ones they originaly sent with the Arctic.

I know for certain that with the original glasses that came with the Arctic the dot from a high power 445 still appears blue, albeit MUCH lower in intensity to the point it has no effect if you stare at the dot reflected of a light matt surface.

The picture you show is more like what I see from my Laserglow shades that block out all of the blue light completely.

Any chance of a video showing the beam being measured with a LPM, and then being interrupted with the glasses?

Let me go shoot that video right now...BBS...



I'll update the review itself with this video tomorrow morning. :)

Well it settles it.

Those are definitely not the same as the ones bundled with the Arctic so far. Even the recent reviews show the same ones I have.

The lenses look much darker too.

Thanks for the review, and clip :)

These are the lasershades that WL has been selling that use the standard 532nm-and-below dye that is known to block 445nm quite well. The actual Arctic Lasershades are the ones that have been shipping with the Arctic...

These LaserShades were sent with my latest Arctic, which was sent out on 11-25-10 (or "25 Nov 2010" if you prefer)...guess I now need to check them with a 532nm green laser and see "whats'a the deal" (as my stepmother Karen used to say)...BBS...

Ok, here's the video:



Note that when the LaserShades intercept the beam, you may still be able to see a dim spot on the sensor. This alone tells me (you too?) that attenuation at 532nm is not 100%. Very good mind you, but not complete.



And here's a photograph of the beam terminus spot from the 80mW Wicked Lasers Phoenix 80mW Green Laser taken after firing the laser through the LaserShades:
