BRIEF COMPARISONS OF INEXPEN$IVE BLU-RAY (VIOLET-EMITTING) LASER PENS

In this post, you'll see informal comparative analyses of those inexpen$ive Blu-ray (violet-emitting) laser pens. This will include the following information about each laser: Cost (in US$), power output and wavelength, construction notes (engraved pocket clip, barrel construction, etc.) plus any characteristic(s) about them that make them better or worse than others. I realise that the previous will be rather subjective, but it might be something to think over.

All but this one use two AAA cells -- this is a pretty universal power source for "pen-style" lasers.

Beam quality and diameter are extremely similar from unit-to-unit, and none of them are focuseable.

So, without further adoo, let's get this show on the road, shall we?




5mW Violet-Emitting Laser Module
Cost: $10.88
Advertised power output: 5mW
Measured power output: 9.610mW
Wavelength: 404.550nm
Construction notes: Reads "Laser Pointer" on clip; recessed shallow "dimples" on lower half of barrel, matte silver tailcap, black matte body
Label color: Red
Seller: DealExtreme
Date of purchase: 09-16-09
Nothing unusual about this one -- pretty run-of-the-mill stuff here.




5mW Violet Laser Module w/"Constellation" Lens
Cost: $12.24
Advertised power output: 5mW
Measured power output: 44.60mW
Wavelength: 403.45nm
Construction notes: Reads "Laser Pointer" on clip; recessed shallow "dimples" on lower half of barrel, matte silver tailcap, black matte body; removeable holographic optic
Label color: Blue
Seller: Ebay find
Date of purchase: 07-06-10
This one has a holographic "stars" optic that can be rotated through a full 360° on its X-axis; this gives hundreds of different "star" patterns.




5mW Violet Laser Module
Cost: $10.88
Advertised power output: 5mW
Measured power output: 61.470mW
Wavelength: 408.19nm
Construction notes: Reads "Laser Pointer" on clip; recessed shallow "dimples" on lower half of barrel, matte silver tailcap, black matte body
Label color: Blue
Seller: Ebay find
Date of purchase: 07-12-10
Nothing unusual about this one -- pretty run-of-the-mill stuff here.




5mw Blue/Purple Laser Module
Cost: $9.50
Advertised power output: 5mW
Measured power output: 57.90mW
Wavelength: 406.40nm
Construction notes: Reads "Laser Pointer" on clip; recessed shallow "dimples" on lower half of barrel, matte silver tailcap, black matte body
Label color: Blue
Seller: Ebay find
Date of purchase: 07-18-10
Same as above -- nothing unusual about this one.




405nm 5mW Violet Purple Blue Ray Blue Laser Module Pen
Cost: $7.86
Advertised power output: 5mW
Measured power output: 15.80mW
Wavelength: 404.40nm
Construction notes: Reads "Laser Pointer" on clip; recessed shallow "dimples" on lower half of barrel, matte silver tailcap, black matte body
Label color: Purple
Seller: Ebay find
Date of purchase: 07-27-10
Same as above -- nothing unusual about this one. Color of warning label is different anyway.




405nm 5mW Violet Laser Module Pen
Cost: 99¢
Advertised power output: 5mW
Measured power output: 30.840mW
Wavelength: 402.92nm
Construction notes: Reads "Laser Pointer" on clip; recessed shallow "dimples" on lower half of barrel, matte silver tailcap, black matte body
Label color: Blue
Seller: Ebay find
Date of purchase: 08-10-10
No other outstanding differences here.



405nm 5mW Violet Laser Module Pen (2)
Cost: $2.90
Advertised power output: 5mW
Measured power output: 49.950mW
Wavelength: 405.00nm
Construction notes: Reads "Laser Pointer" on clip; recessed shallow "dimples" on lower half of barrel, matte silver tailcap, black matte body
Label color: Blue
Seller: Ebay find
Date of purchase: 08-11-10
Again, no other outstanding differences here.




5mW 405nm Violet Purple Blue Beam Laser Pen
Cost: $2.90
Advertised power output: 5mW
Measured power output: 47.61mW
Wavelength: 407.90nm
Construction notes: Reads "Laser Pointer" on clip; recessed shallow "dimples" on lower half of barrel, matte silver tailcap, black matte body
Label color: Blue
Seller: Ebay find
Date of purchase: 10-06-10
Once again, no other outstanding differences here. Like most on this web page, it appears to be extremely similar to other ones, as though it had come off a cloning machine.




Mini Purple Class Laser Beam Black Keychain
Cost: $7.99
Advertised power output: 5mW
Measured power output: 23.110mW
Wavelength: 401.10nm
Construction notes: Shorter than other "pen-style" lasers; no pocket clip (has keychain attachment though)
Label color: Red
Seller: Ebay find
Date of purchase: 10-06-10
I really like this one mainly because of its form factor -- it uses one AAA cell instead of two, subsequently making it significantly smaller than other "cheapie" Blu-ray lasers.




405nm 5mW Violet Purple Blue Beam Laser Pen
Cost: $10.66
Advertised power output: 5mW
Measured power output: 57.30mW
Wavelength: 405.00nm
Construction notes: Reads "Laser Pointer" on clip; recessed shallow "dimples" on lower half of barrel, matte silver tailcap, black matte body
Label color: N/A
Seller: Ebay find
Date of purchase: 10-06-10
This one has no CDRH-mandated laser warning label; all lasers sold in the US must have one.
Otherwise appears very similar to the other 2xAAA cell pens on this web page.




10mW Blue-Violet Laser Pen
Cost: $8.99
Advertised power output: 10mW
Measured power output: 75.50mW
Wavelength: 405.70nm
Construction notes: Reads "Laser Pointer" on clip; recessed shallow "dimples" on lower half of barrel, matte silver tailcap, black matte body
Label color: Blue
Seller: Amazon.com (www.amazon.com...)
Date of purchase: 02-04-11
The highest power output of the non-modified "pen-style" lasers in my custody.
Otherwise fairly unremarkeable.




Violet Purple Blu-ray Laser Pen (1)
Cost: $2.99
Advertised power output: 10mW
Measured power output: 22.50mW
Wavelength: 404.95nm
Construction notes: Reads "Laser Pointer" on clip; recessed shallow "dimples" on lower half of barrel, matte silver tailcap, black matte body
Label color: Purple
Seller: Ebay find
Date of purchase: 02-04-11
Nothing outstanding here folks.




Violet Purple Blu-ray Laser Pen (2)
Cost: $5.55
Advertised power output: 5mW
Measured power output: 53.50mW
Wavelength: 405.65nm
Construction notes: Reads "Laser Pointer" on clip; recessed shallow "dimples" on lower half of barrel, matte silver tailcap, black matte body
Label color: Blue

Date of purchase: 02-20-11
Nothing that sets it apart from the pack.




Violet Purple Blu-ray Laser Pen (3)
Cost: $6.65
Advertised power output: 5mW
Measured power output: 53.70mW
Wavelength: 404.65nm
Construction notes: Reads "Laser Pointer" on clip; recessed shallow "dimples" on lower half of barrel, matte silver tailcap, black matte body
Label color: Blue
Seller: Ebay find
Date of purchase: 03-20-11
Again, nothing different about this laser than most of the others here.
