Focusing Lens F800 (2pcs)

F800 focusing lenses for 4in1 laser welding machine (cleaning mode)

A focusing lens, made out of quartz, in laser machines is a critical optical component that concentrates the collimated laser beam to a fine spot, enabling precise cutting, welding, engraving, or cleaning. the lens is coated with an Anti-reflective (AR) for fiber laser (1064nm wavelength)

• It takes the parallel beam produced by a collimating lens and focuses it to a specific point.

• This focus point is where the laser's energy density is the highest—ideal for material interaction (cutting, cleaning, etc.).
