I'm sorry - the A and R is wrong for Arial - this is Helvetica.
I had to blow it up to see what was going on...

I do believe it to be Titillium, and you hopefully have it in your font collection already.

Titillium - perhaps you already have it...

mixture of upper and lower case

The "F"

Again - another three font logo ... not two

"alcon" is in Vivaldi - no doubts...

The capital B

English though it also matches Shelley Andante - chalk it up to different manufacturers of the same font with different names most of the time...

Good old Vivaldi
