WTB: 445nm 5mw

I am looking for a 445nm pointer with only 5mw of power, preferably waterproof.

Thanks!

How waterproof (estimated depth)?
and
How much are you willing to pay?

I don't think I have seen a waterproof low-power 445nm laser for sale commercially, but it can be built for you.
FYI - a 445nm diode that can lase at 5mW (low power) will be about $60-$80 (for the bare diode).

I have a spare waterproof host (my 405 died) all you'd need is a single mode 445 and run it at threshold current.

If you can be bothered building your own that is.

Im still new to all of this... I know green appears to be the brightest to the human eye, but I suppose I'm looking for something around the brightness of a 532nm at 5mw, or slightly dimmer, but not much....

I guess weatherproof would've been a better term.... maybe a few meters deep, mostly rainproof is what I really want...

Not sure on how much to spend, maybe around $100, but again, I'm new to this, so my judgement on allowable cost may be skewed. I'm mostly trying to gather info on what I want and how much it will cost me. Thanks for the info and help.

waterproof green ~5-50mw will be much cheaper than a low powered 445 for your application uses (unless you LOVE blue )

what if we used a zombies 445 diode?
would you be able to lower the threshold? (since its less efficient at the same current)

Get a single mode blue at around 50mW's, that would = around 5mW's of green

Why 5mW and waterproof? You plan on lecturing in a rainstorm. :undecided:
For $30, you could buy a cheap green waterproof one (link) and turn the potentiometer down until you get 5mW.

A waterproof blue at 20-50mW will have to be custom made and will cost ~$100

lol... I already have a cheapo green 532nm (well, wasnt that cheap when I purchased it, its a dpss from around 2005, or whenever these first started being manufactured and converted to green, cost me around $80, but cheaply made, probably not true 5mw) ...anyway, I've always wanted a blue laser pointer ever since I knew what a laser was, I remember back in the mid to late 90's getting my first red one thinking it was the coolest thing ever, however, blue is my favorite...
Weatherproof is a better term for what I want, basically I want it protected from moisture just in case. I mostly just want a toy (yes I know lasers are NOT "toys" by any means, but for lack of a better word..) thats why I want a lower powered one
~$100 is my limit, depending on what is able to be purchased/custom built

EDIT: I'd also prefer the housing to be black or gunmetal, not much larger than a pen or small flashlight, maybe close to the size of a Surefire LX2 Lumamax or smaller, and scratch proof/resistant to withstand being in a pocket with keys and such. Similar to this look

Willing to pay to have this custom built for me

I have that host, but silver. If you can find someone to custom build a single-mode 450 into it I'll send them the host to put it all in as a Christmas gift for you.

You can also get them custom painted if you wish.

That would be awfully nice of you, especially with me being a new member here. I'm not sure what it would cost me to get it custom painted black, I'd like it to not scratch off easily.

After actually having a little bit of time earlier today to search around a bit, I'm actually really liking this kit even though its not black. I would really love this host with a 50mw diode toned down to around 20-30mw or so.

I still haven't researched enough to know if I want to build it myself or have
someone else build it. I also dont know what type of lens or driver to use or anything like that yet, still trying to read and learn. I am willing to pay more $ for better/best quality.

Any recommendations, anyone?

there is no such thing as a "50mw" blue diode
they are all ~1300mw tuned down to whatever
thats why the diodes all cost the same price (~$45)

you might get a better deal if a builder uses a zombied diode with your build (saves both ways)

A single mode 450 diode are what he wants. I've only seen them go up to 100mW so far.

I have seen 445nm diodes at 50mw somewhere, with 80mw max power I think, not sure where I came across them, I'll edit this post when I find them later.

EDIT: Found it:

here is a thread

which also contains these links in the first post:
OSRAM 450nm 80mW Diode - $79 - www.o-like.com OSRAM Diode
OPNEXT 450nm 80mW Diode - $59 - www.rayfoss.com OPNEXT Diode

Apparently they are both the same diode

I believe Max at Lazerer uses the lower power 445nm diodes in his "mini B" builds. They are within your budget but not waterproof/resistant.

I agree about the desire for weatherproofing though, the only reason I dislike "pointers" over handhelds is the momentary pushbutton and that pointers are easily affected by moisture ingress. The smaller form factor of a pointer makes it a lot easier to keep with you, and if it's with you more, you can enjoy it more.

I agree totally. The mini b isn't too bad.

I really really like this kit and would like to have it custom built with the single mode 50mw 445nm diode, toned downed a little, to around 20-30mw. After searching around, and really wanting something to carry, I really like the small form, more of a pointer style I suppose.
