Description (Plano-Convex & Plano-Concave)
This series of glass focusing lenses are made of BK7 (LBK) or Fused Silica (LFS); light enters from one side and exits from the opposite side. Its purpose is to modify the wavefront curvature of the light through the lens. Then, focus the laser beam onto a very small precise spot size so that it is widely used in engraving graphic images, welding metal pieces together, or cutting various types of materials. We have different coatings and materials for different wavelengths.
