Default Need help finding IR laser Diode with the following specs

Hey guys I'm new here and I'm a really big noob on lasers. I'm looking for an IR laser Diode with the following specs

Class: IIIb
Output Power: 600 microwatts
Wavelength: 830nm +/- 20nm

I've been looking around but I haven't been able to find a IR laser diode with the output power of 600 microwatts.

This is for a project I'm undertaking for replacing the visible laser diode of a laser weapon sight (Insight M6X) to an IR laser.

(Also if anyone has undertaken this feat please let me know how you did it LOL)

Thanks guys!

600microwats is not class IIIb, class IIIb is 5-500mW.

Sorry about that I was going by what it said in the manual. Thanks for the clarification.



I guess 500 MW would be enough. Thanks

I'm trying to switch the laser on this so I can use it in conjunction with Night vision.

I have 500mW 836nm NIR diodes.. They are c-mount though.
Dont know if you will find the range your looking for in 5.6mm or 9mm LD's.

I'm not quite familiar with Laser related terms.

C-Mount?

Default Re: Need help finding IR laser Diode with the following specs

What type of night vision?
And what wavelength is the laser that is currently installed? I'm guessing 635-660nm?

600 microWatts (W) is equal to 0.6 milliWatts (mW), so 600W is Class I.

Regardless, you may be able to use any diode >780nm. The output power you need is determined by the kind of illumination you require.
780nm and 808nm diodes are the most common and cheapest near IR diodes available and in a wide range of power outputs.

Current wavelength is 640nm +/-40

I'll be using the IR laser with ITT Gen III PVS-14s

something like this 3mW module for $4 will work great for you. Night vision isn't wavelength dependent and can often see anything down to 990nm or more. If you're feeling particularly adventurous, you can use the diode from any old CD drive.

Class 2, you mean. Class 1 has to be <390W according to wikipedia.

There are individuals who offer this service for a fee already.
But be prepared to pay $75+ for the service or more for entire rebuilt unit.
