Focal plane of the RMI cylindrical lens (lens6).
- RMI cylindrical lens (r1=33, r2=24, thickness=13.12 mm)
- d - distance between incoming laser beams
- focal length is calculated from a focal point to the closest layer of the lens
- photon energy = 3.18 eV (~400 nm)
Example with two pairs of parallel beams at different angle. Focal points are calculated as an intersection of beams of each pair after the lens.
