5mW* 445nm pointer from laserlands

[jimdt7]

Nice little review !
Cant wait for beamshots !

 

[Cyparagon]

Beamshots aren't going to look any different from the blues you're used to, but I'll grab a few later if you want.

Hmm. Very nice. Can you see a visible wavelength difference from 445? Or are they too close to see a visible difference...

No, they look the same. Keep in mind 445s actually vary from 440 to 455.

How would this be as a presentation pointer?
Is 50mW of 449nm dim enough to use in a conference room on a whiteboard?

It's about as bright as 10mW of green, so it's a little on the bright side for a dark room. A lit room shouldn't be a problem.

but would you buy a 50mW 445nM ?

Because if I want to burn things, I use a lighter or a CO2 laser. Judging a laser just by the power is short-sighted. I contend this pointer is actually more useful than a 2W cannon.

I attempted to find this laser on the Laserlands website but was not successful.
I'm interested in getting one, yes.

Interesting review and nice pointer

I'm totally agree!!!!

looks great! this is also $10 cheaper than the ones i saw + free shipping. (although, i really hate dealing with Hong Kong Post).

also found this one -seems legit. uses the osram diode

^^^ Thank you^^^ for the link -- as soon as my money comes, I'll be purchasing one. :thumbsup:

Thanks +Rep :beer:

What is the maximum output for singled mode diodes on the market today?

I know nLight has 808nm C-mount diodes doing over 5W:

:eg:

 

[Cyparagon]

^Single-mode, not single emitter. The opnext blues are the highest (commercially viable) I know of for blue - they supposedly do 80mW max. That may be what's in this pointer.

I think the 12X blurays are the highest power single-mode overall.

Oops
:banghead:

 

[bennett326]

very cool anyone know where you can buy bare diodes are they even available?

btw guys burning gets old fast

my favorite laser ATM is a phr

 

[LtKernelPanic]

Nice. If I wasn't broke ATM I'd be all over one of these. I'd like a blue that I can show people without worrying about blinding them.

Heh the prrevious poster mentioned that their current favorite is a phr build because while not my all time favorite my phr build is still in my all time top 5.

Yes.
O-like has OSRAM ones for $80 --> Link
Rayfoss has OPNEXT ones for $59 --> Link
:san:
(osram=opnext?)

 

[Arayan]

BTW I suggest to change the thread title with 50 mW...

 

[bitmerge6502]

What kind of driver would i use for the osram 450 if i wanted to make a keychain pointer? it would have to be powered by a single AAA battery (1.5v) because of the host i want to use.
