Achromatic Lenses

Achromatic Lenses consists of two positive and negative lenses with different refractive indices bonded together. They have corrected for spherical aberration at both axial and paraxial points. When a double-bonded lens is used for focusing or collimating, the surface with a small radius of curvature faces the collimating light.The optical performance of achromatic double-bonded lenses is much better than that of single lenses and is suitable for demanding imaging and beam control needs.Our lenses are carefully processed, strictly controlled quality, to ensure that at a reasonable price to provide users with high quality lens products.
