Fac/sac 40 watt burning

[ducatidragon916]

So I had to create another thread as I could not reply on my other thread maybe it was a glitch on this page or what?
The lenses is set on the die and I am able to get a burn as you can see on the image. This burn happens when I am almost on top of the lens combo and not when I at a distance. Somehow the lens doesn’t help with dispersion. I will be obtaining a aspheric lens to check and see if I can improve the focus of the beam to increase the power density etc.

As you can see in the image I attached the lens combo to the 40watt die and the output of a width wise configuration. Should I consider glueing down an array of fiber optic fibers cleaved so I can direct the beam with more control? If I do this an aspheric lens would be eliminated as well

You are dealing with a strip of many emitters, maybe after your fac lens you want to use a cylindrical and then an f-theta lens.

So i dont really need extra fiber knife edged type configuration?

 

[ducatidragon916]

Actually it is a combination lens with a sac lens at the other end etc. So what diameter type of glass rod would you recommend or is there a calculation based on several factors?

I don't know the specs on your emitters.
You could contact Thorlabs or Edmunds or another optics company with your part number.
What are you attempting to do? What do you want to accomplish?
