Which violet/purple Laser to buy...

Neroy · Jun 13, 2010

So I've been looking around a lot because I'd like to buy a purple laser pointer.
Blue is nice too but that new WL model is just to high in power for my liking, in any case which purple laserpointer is a good choice? Dragonlasers offer a 80mW one, WL a 20mW one thats more expensive than DLs for whatever reason.
I couldn't find any helpful info, reviews or videos on purple lasers so I was hoping for some adivce here.
Also is the 80mW purple lasers beam visible?

this pic is of my 20 mw pointers from a ways back, so yes beam is visible.

Thanks for those pics and the info although I already covered a decent amount of it while I was just lurking around these forums for info ^^
In any case I saw how people prefer some sites in regard of the quality of lasers so I'd like to get some peoples opinion which laser they would buy and from what site.
So far Dragonlasers is the only site I saw a 80mW purple laser, pretty expensive though.
The ones from Wickedlasers have a nice design and all but are also quite expensive and don't have as much power output (5mW or 20mW versions)
I guess you can't only judge from the mW alone though.

That pic is very misleading. My 100mw bluray is hardly visible at all.

Lazerus · Jun 21, 2010

Ledshoppe.com recently added a 50mw 405nm ($24.99) UV pen laser to their inventory. I'm de-lighted with mine. Coupon code 1030 or 1560 for $30 & $60, respectively.

It depends on the air quality, and your eye sensitivity to 405nm. I can see my ~100 PHR builds quite easily.

Burnsy · Jun 21, 2010

Look at the sites from O-like or especially Rayfoss
I think they got some solid products (405nm pointer&torch) that are also quite cheap

Have you made 100 PHR lasers? or did you mean you can see your ~100mW PHR easily??
lol
cheers

i just got a 150mw violet from o-like. they also have 200mw but i liked the 150mw casing better. cheap too, but its generally accepted round here that 0-like are reputable.

Exerd · Jun 24, 2010

I second to dismiss that pic.

OK, first, the green beams look brighter and more solid than my 475mW green.

The purple looks brighter and more solid than my 800mW+ blu-ray.

There is no way in hell you can tell him that's what 20mW looks like. That's just wrong. Maybe in a room filled with smoke and the camera oversaturating the photo.

He should at least know that a 100mW BR laser is not going to be that bright of a beam. It will in fact be visible, but quite dim.

As I stated earlier, that is not true. I was just camping and the whole camp could see my beam quite clearly. They all came running up because they had no idea what it was. I shot it at a nearby mountain over a lake and you could see the beam refection off the lake.

Maybe you live in a cleaner air environment than we do, Maybe you dont see 405nm that well. I had some pix on my old dead PC of beam shots in my house with the lights on, during the day.

Wayne's pix were taken in the dark, so naturally he is going to get a longer exposure, but they are not that far off.

Here is one of my lobster and you can clearly see the beam reflecting off his claw. If it was not that bright, there would be no reflection. This is ~170mW.

It is true.

What is not true is our standards of "bright" being equal.

Tech_Junkie · Jun 24, 2010

If your eyes are not sensitive to 405nm, then how can you tell exactly what is bright, and what is not? If you live in an arid, clean air environment, how can you see the beam?

You cant.

Blu-Rays are florescent. If there are no particles in the air, of course the beam will be dull and less bright. Maybe non existent. If your eyes dont see 405nm that well, then of course other wavelengths will be brighter.

You have high powered lasers, but if there is no particles in the air, they will look dull, compared to high pollutants and a low power laser.

Also your diode may be below 405nm, making it even harder to see,

nikokapo · Jun 24, 2010

You both need to sort out your differences. Clearly the solution is just setting a reference point that will help Neroy. If you compare the 405nm to a 532nm laser, the beam will be "dim". If you just want to see the beam, a 100mW PHR as TJ said would be a good first laser. The beam IS visible, but not to the same extent as you would expect from a green laser; just use the violet laser in a very dark environment and you'll have no trouble seeing the fine line.

Benm · Jun 25, 2010

Comparing side by side, any 405 nm laser would look dim. It seems to depend on the person a bit, but to me 5 mW of 532 seems brighter than 100 mW of 405.

Tech_Junkie · Jun 25, 2010

I was never arguing the point that 532nm wasn't brighter than 405nm. Just the fact it was possible that 20-100mW 405nm can be just as bright, if not brighter than an 850mW 405nm in certain conditions. Is this wrong?
