  • Glass Focusing Lenses

This series of glass focusing lenses is 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.

  • ZnSe Focusing Lenses

ZnSe Plano-Convex Lenses (LZ) has a positive focal length and are used to focus a collimated beam to small spot size. ZnSe Plano-Concave (LZ) lenses have a negative focal length and are used for diverging collimated beams. The curved surfaces of these lenses should face the source to minimize spherical aberration. Positive Meniscus Convex-Concave (LZM) Lenses are converging lenses being thick at the center and thin at the edges and produce real images. The radius of the curvature of the concave side is greater than the convex side of the lens. The convex side of the lens should face the source to minimize spherical aberration. It is designed to minimize spherical aberration and produce minimum focal spot size for incoming collimated light.
