The cd lens on this unit trys to focus on the disc but there is no
beam from the lens. How do I check the lens?

If there is no beam from the lens, then the laser is either dead or not
being turned on.

But, the laser in a CD player is 780 nm, near IR, and close to invisible.
It's not bright like a DVD player's laser. Just a faint red dot in the
when viewed from the side.
