ARCTIC 445nm LASERSHADES

Arctic 445nm LaserShades, retail $29.99 (www.wickedlasers.com...)
Manufactured by Wicked Lasers (www.wickedlasers.com)

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 two 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.

This is what the Wicked Lasers Spyder 3 Arctic 445nm 1W Blue Diode Laser did to these LaserShades.
I have two other pairs of laser safety goggles that are highly effective at the Arctic's wavelength; so I was easily able to sacrifice these LaserShades in the name of science without robbing myself of eye protection.

Spectrographic analysis of daylight to use as a control.

Note the sharp decrease in transmission between ~450nm and ~500nm.

That broadband "hump" peaking at ~615nm is fluorescence from the lenses of the glasses themselves.

Video on YourTube showing the Wicked Lasers Spyder 3 Arctic 445nm 1W Blue Diode Laser irradiating and subsequently destroying these safety glasses (that were furnished with that laser).

This clip is approximately 20.335662378675 megabytes (20,582,520 bytes) in length; dial-up users please be aware.
It will take no less than one hundred two minutes to load at 48.0Kbps.

I cannot provide this video in other formats, so please do not ask.

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 on "low" was measured at 3.00mW, and on "high" it measures 20.96mW.

But with the Medical P/C Argon Laser Safety Goggles intercepting the beam, the power reaching the laser power meter with the Arctic set to "low" was just 40.000琺 maximum; most of the power is from the yellow fluorescence of the lenses themselves, and 2.12mW with the Arctic set to "high" -- again, virtually all of it is from the yellow fluorescence of the lenses.

TEST NOTES:
Test unit was furnished with the S3 Spyder Arctic 445nm Blue Laser that I received from www.wickedlasers.com on 09-27-10 (or "27 Sep 2010" if you prefer).

The primary reasons that this product received 3 stars and not 5 is because the transmission at the 445nm design wavelength is still quite a bit high, and because they offer no protection against laser radiation coming in from the sides, top, or bottom.
