In order to figure out which one is best for your laser its best to think about how you are going to mount it.
The different lenses give you the option of mounting it at different heights from the cutting bed while still being able to see the whole bed.
In order to determine the minimum height for the camera to see your whole laser area, use the wider of the two lengths of your system and divide by:
2.7 for the 160 degree lens
1.8 for the 140 degree lens
1.5 for the 120 degree lens
1.4 for the 90 or 80 degree lens
0.825 for the 60 degree lens
For example, on a 700 x 500 mm laser, using the 140 degree lens you would divide 700 by 1.8, giving a minimum height of 389 mm above the bed to see the whole thing.
For most users, this will mean mounting the camera to the open lid of the laser. The 160 degree lens gets you much closer, only 259mm high with a 700mm wide bed.
