Fiber Laser Focusing Lens / HFTLSQ_HFDLSQ
By using synthetic fused silica as the material for all constituent lenses, we have achieved a focusing lens that can withstand high-power lasers and high-energy pulsed lasers.
They are suitable for focusing and collimating solid state lasers like Yb fiber laser, YAG laser and YVO4 laser.
