1 watt 808nm laser build for 75 bucks.

Seems like you forgot something very important :

Laser safety goggles?

I don't see them anywhere, so don't forget you need good ones for that power of IR.

Yeah, I got those too. I'm getting them from a store nearby, but they don't have a website, so I found the same pair online:
Laser Glasses - Near Infrared (IR) protection 750-850nm :: Laser Safety :: Dragon Lasers
I do like the use of my eyes, so I won't forget these.

We know where to get them but for $30. I want to know where he got one for $6.

There aren't that many, but I bought from the seller in Santa Fe, and it got here quick (I live in Florida)

Does this guy have more 9mm modules?
If he has, can you give us item number.

650nm 5mW (Red) laser module CROSS 3VDC 9mm X 20mm - eBay (item 160341335168 end time Aug-09-09 20:03:50 PDT)

All the listing says is that he has more than ten available.

Scratch the 75 dollars, it now looks like I'm spending around 100 because I can't find a cheaper high quality 9mm lens than the one Dr.Laser suggested.

Size (D×L ) : 9×20(mm)

Doesn't it mean 9mm is outer diameter?

 

[FireMyLaser]

Obviously.

The same seller sells module with dot lens.
I asked him which diode is inside this module
5mW Red Laser Module DOT 6mm X16.8mm - eBay (item 150351248766 end time Aug-09-09 20:09:17 PDT)
He answered 9mm diode.
So I asked him which is outer diameter and he didn't reply yet.

 

[FireMyLaser]

How the f could a 9mm diode fit inside a 6mm module?

That seller is trying to screw you.

 

[ReNNo]

That is for sure.

Any other recommendation where to find 9mm module?

 

[BuildAbluraylaser]

all I know of is Meredith Instruments - The Source for Lasers, Mirrors, Optics, Parts, and Surplus

 

[ReNNo]

We know about that web site
But I need $35 for module with glass lens.
hahaha

 

[BuildAbluraylaser]

Ok, well that's the best place to buy those, but try looking on ebay...

 

[ReNNo]

There is another seller that sells "9mm modules"

http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=110413642493&ssPageName=ADME:X:RTQ:US:1123

And this is his answer:

Dear Sir or Madam,
Thank you for your enquiry.
It's 9mm diode.
We are sorry the supplier did NOT provide a
relative information about outer diameter of
module or glass lens inside module or acrylic.
If we may be of further assistance, please contact
us again.
Best regards

I'm not sure, the module is 9mm too, that means that the thickness of the module walls is 0mm.

Impossible.


And also, low power module like those use small less powerful 5.6mm laser diodes; 9mm package are the ones that provide more power.
