I need to determine what lens will work best for my application. My source of light is an LED COB array, which has an LES of 32mm. I need help determining if an Aspheric Lens will work to collimate the beam to ~35-60degrees. If it will work, I would like to know what specifications I need in the aspheric lens to accomplish my goals. Let's talk more.

I can see that you are targeting a focal length of around 10 to 20mm. While the the FOV you are targetting is quite large, the question whether you should go for aspheric optics or not is dependent on the quality of the collimation you are looking for. It also depends on what F# system you want. Looking at your system, it seems you will be going for F# at least 0.8 value. Have you considered any optics yet? Which vendor have you selected? Let me know more in chat. Have a good day.
