Info for purchasing eyeware

Hello everyone

I have been asked to provide some information to an eyeware and screen supplier regarding the IR1064 2W & the 20w modules.

Beam diameter at 10cm from output or focus?

Beam diameter before focusing and focal length?

Beam diameter at output and corisponding divergence?

I’m hoping someone on the forum can help with these questions as I’m having trouble finding the info elsewhere and the info provided by SM was not enough for the supplier.

Kind regards

Pete
