Product Description
A laser plano convex lens is a fundamental focusing optic, designed with one flat and one convex surface to provide positive focal length. It efficiently focuses collimated beams into a spot or collimates point sources into parallel beams. For reduced spherical aberration, beams are directed to the curved side.
Performance Advantages
High transmittance and low absorption ensure stable laser energy transmission
High laser damage threshold, suitable for high power laser systems
Precision surface processing, better than 20-10
Reduce spherical aberration design and improve beam focus quality
Multi-wavelength adaptation, covering 355nm, 532nm, 1064nm
Application Range
Laser marking, cutting and welding
Precision laser processing equipment
Scientific research optical experiment platform
Laser beam shaping and focus
Industrial and medical laser systems
