Θ1= mrad
 
 
y1= mm  
f= mm

For best results:
  1. Please enter a focal length (f) that is larger than the beam diameter (2*y1)
  2. Please choose a plano-convex lens or a microscope objective.
Inputs Outputs:
y1: beam radius y2: image height
Θ1: beam (half-angle) divergence Θ2: beam convergence angle
f: focal length s2 : lens to image distance
