• Plano-Convex & Plano-Concave • Air Spaced • Achromatic Cemented Glass Focusing Lenses 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. Air Spaced Glass Focusing Lenses The purpose of developing an Air Spaced Glass Focusing Lens is to minimize aberration and achieve the smallest spot size. The achromatic triplet focusing lenses are color corrected. Both working laser beam and inspection visible beam will focus on the same focus point or two closest ones. Achromatic Cemented Glass Focusing Lenses These are cemented doublet lenses for 1064nm laser, as well as colour corrected for visible wavelength. They are made up of a combination of low dispersion crown glass and high dispersion flint glass. They are suitable for laser cutting and welding applications where a vision system is equipped.
