1mW 405nm Blue Violet Laser ~~Pointer~~ PORTABLE LASER Military Exclusive, retail £10.90 ($17.83*)
Manufactured by: (Unknown)

(In reference to the padded envelope I received from an Ebay seller at 3:47pm PDT on 05-10-11):
{sung like the Foreigner song "Feels Like the First Time"}

The 1mW 405nm Blue Violet Laser ~~Pointer~~ PORTABLE LASER Military Exclusive (hereinafter, just called a "Blu-ray Laser Pen) is a violet-emitting, directly-injected laser. That is, it produces violet laser radiation directly, without the need for messy, fragile nonlinear crystals like those green laser pointers and the amberish-yellow and blue ones as well. It uses two AAA cells -- the same power source used in most other "pen-style" laser pointers and laser modules.

It is advertised to output less than 1mW of laser radiation at ~405nm.
It actually measures 22mW at 404.266!!!
This is the reason I call it a "portable laser" on this website instead of a "pointer". Lasers designated as "pointers" must -- by US law anyway -- have a power output that does not exceed 5mW.

It comes in a handsome brass body with a black finish and chrome colored bezel, tailcap, and pocket clip.

SIZE

To get the laser to turn on, first be certain that there are a pair of AAA cells installed. If there aren't, then install them (see directly below), and THEN you can go irradiate something.

Aim the laser well-away from your face first.

Press & hold down the button on the barrel for as long as you want or need the laser spot, and release pressure on the button to turn the laser back off.

To change the batteries in this violet laser , unscrew & remove the tailcap, throw it into the dustbin (garbage can), tie off the bin liner (plastic garbage bag), carry it to outdoor wheelie bin (wheeled garbage can), throw it in, slam the lid down, and wait patiently for garbage day so that the dustman (garbage man) empties the wheelie bin into his dust lorry (garbage truck)...O WAIT!!! THAT'S THE GOOD PART!!! So just set it aside instead.

Tip the two used AAA cells out of the barrel and into your hand, and dispose of, recycle, or recharge them as you see fit.

Insert two new AAA cells into the barrel, flat-end (-) negative first. This is the opposite of how batteries are installed in most flashlights, so please pay attention to polarity here.

Screw the tailcap of the tube back on, and be done with it.
Aren't you glad that you didn't throw that tailcap away now?

Current usage measures 114.70mA on my DMM's 400mA scale.

This is a self-contained laser , and not a flashlight meant to be carried around, thrashed, trashed, and abused - so I won't try to drown it in the toliet tank, bash it against a steel rod or against a concrete porch, let my mother's big dog's ghost or my sister's kitty cats piddle (uranate) on it, run over it with a 450lb Celebrity motorised wheelchair, stomp on it, use a small or 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. So this section of the web page will be ***SIGNIFICANTLY*** more bare than this section of the web page on a page about a flashlight.

This is a directly-injected laser though (which by their very nature are more rugged than DPSS lasers!), who's active components are the inverter circuit, the laser diode, and the collimating lens. So it should withstand accidents better than a DPSS (diode pumped solid state) laser - the type of laser assembly found in deep red (671nm), yellow (593.5nm), green (532nm), and light blue (473nm) laser pointers. These lasers have several additional components (crystals, filters, etc.) in the optical train, and you can knock them out of alignment by doing little more than looking at them the wrong way. And if any of these components are knocked out of whack, you'll no longer get your deep red, yellow, green, or blue laser beam.

Though you still do not want to intentionally drop your violet-emitting laser because it's a precision optical instrument.

***EXTREMELY IMPORTANT!!!***
This laser has a fair amount of {vulgar slang term for male nads} to it (measured at 19.00mW), so you ***DEFINITELY*** do not want to shine it into your eyes, other people's eyes, pets' eyes, for that matter, the eyes of any person or animal you encounter.

Eye damage can occur faster than the blink reflex can protect them, regardless of what species' eyes you irradiate with this laser. So just don't do it.

And para los motivos de Cristo (and for heaven sakes and for Pete sakes and for your sakes too) do not shine this laser at any vehicle, whether ground-based like a motorcycle, car, or truck, or air-based like a helicopter, airplane, or jet. And if you shoot it at a person in the dark and he turns out to be a police officer, he may think he's being targeted, unholster (whip out) his gun, and hose you down with it.

Does this evaluation look an awful lot like the one I made for this laser?
Thought you'd say so.
That's because they're functionally identical, so I was able to use its web page as a template for this one.

Power output analysis

Power output tops out at 22mW on a LaserBee 2.5W USB Laser Power Meter w/Thermopile.

Beam terminus photograph of this unique (well, "not-so-unique" now) laser on the target at 12".
Beam image bloomed ***SIGNIFICANTLY***.

That white & blue color does not really exist; the spot appears to be a very deep royal purple to the eye.
Digital cameras have a tough time at these wavelengths.

And yes, I know that the colors purple and violet are two different critters, but the phrase "royal violet" would not make very much sense; however, most everybody knows what "royal purple" looks like.
Purple is a mixture of red & blue; violet is a spectral color, encompassing wavelengths of ~390nm to ~410nm.

Measures 19.00mW on a Sper Scientific Pocket Laser Power Meter # 840011; using known-new AAA cells.

Beam terminus photograph on a wall at ~10'.
Again, that white & blue color does not really exist, and beam image bloomed a bit.

Spectrographic analysis of the Blu-ray laser diode in this product.
Wavelength appears to be ~405nm, which is within specification for the type of laser diode used in this laser.

Same as above; but spectrometer's response narrowed to a band between 400nm and 410nm.
This shows that the wavelength is in fact 404.65nm.

Spectrometer's response narrowed to a band between 402nm and 406nm to pinpoint wavelength, which is 404.266nm.

Spectrographic analysis of the fluorescence of a uranated* glass marble when irradiated with this laser.

Spectrographic analysis of the fluorescence of the 2009 NIA Commemorative Insulator in uranated* glass when irradiated with this laser.

*"Uranated" - infused with an oxide of uranium, *NOT* piddled (urinated) on.
Commonly referred to as "Vaseline glass" because it has
a distinct pale yellow-green color when not being irradiated.

Note spelling: "urAnated", not "urEnated","urInated",
"urOnated", "urUnated", or sometimes "urYnated".

TEST NOTES:
Test unit was purchased on Ebay on 05-01-11 (or "01 May 2011" or even "May 01, Twenty Double Sticks" if you prefer) and was received at 3:47pm PDT on 05-10-11 (or "10 May 2011" or even "May 10, Twenty Double Sticks").

I have decided to rate this wonderful little laser four stars!!!

If something happens down the road, I can always derate it if necessary.

UPDATE: 00-00-00

PROS:
Color is very radiant & unusual for a handheld laser
Uses inexpensive and readily available batteries
The price is right!
Color is very radiant an unu...o wait, I said that already!!!

CONS:
Just the usual suspects for laser modules/pointers - nothing that affects rating...actually, there is one little thing: it is advertised as a <1mW laser (and has a CDRH Class II warning label on it), but outputs 22mW of laser radiation.
That's what lopped that last star off.
