Default Re: 5Watt portable c-mount ir

I think that a 500mW green system would require a 2.5W pump.. A 2.5W cmount should take around 3.25A, give or take a little. That wouldn't be enough to run a 5W which requires around 6.5A (source)..

Default Re: 5Watt portable c-mount ir

Well I have 2 diodes here and the specs say that they can run 4 watts at 5 amps. I am just not sure if I will be able to get 5 amps out of that driver. I will find out tonight if 3.25 Amps is even enough to get a couple watts out of them.

You should definitely get a couple watts out for 3.25A in, and with a VERY long diode life expectancy as well.

Awesome. I will let you know how it goes tonight. Thanks for the help and the link to that nice resource.

Default Re: 5Watt portable c-mount ir

So it puts out 1 watt with this driver. I don't have any lenses to use with it but burning way up close to the diode is lots of fun. I am going to stop this build right here though and offer it for anyone who wants to pick it up. Soon to be in the BST section.

Default Re: 5Watt portable c-mount ir

What's the build like? Or do I have to wait until it shows up in BST? , also, you might be able to use any convex lens you've got laying round.. even a magnifying glass might get you focused enough to burn. You'll want to be careful burning up close to the diode.. wouldn't want any smoky buildup on the facets.

Default Re: 5Watt portable c-mount ir

Good point, I am not going to try to focus it. I really should have IR goggles and I don't so I don't want to mess around with it too much. I'll go ahead and post it in the BST section now.
