Fiber Laser Focusing Lenses
- Lens optimized to reduce the effect of thermal expansion by unsing all fused silica elements
- High performance Multi-Element lenses, suitable for focusing and collimating solid state lasers such as Yb fiber laser, YAG laser and YV04 laser
- Optimized AR coating from 1064nm - 1150nm: maintain Transmittance at 633nm for HeNe pointing lasers
- Corrected for spherical aberration and coma @1064nm. Lens is diffraction limited for f# >2(NA<0.25)
