SUMMARY
This discussion focuses on the comparison between GRIN lenses and aspheric-convex lenses for laser beam collimation, particularly in the context of a delicate fiber laser focusing system. The user, Fritz, seeks insights on the optical advantages of each lens type, especially for reducing a 4mm beam to 0.05mm in a marine environment. Andy points out that GRIN lenses are suitable for specific applications but suggests that bi-convex lenses may outperform GRIN lenses in terms of spherical aberration quality.
