Laser of CD-ROM-drive

the picture shows the Laser unit of the CD-ROM drive my Laptop. I took the picture to evaluate the optical capabilty of the AF20-80 lens working together with screwed-on macro lenses. I used a 4 dioptre together with a 3 dioptre and a 2dioptre = 9 dioptres in total. I'am suprised at the quality of the picture. At this place I present only the cut-out of the Laser Unit from the original picture.
