Broadband AR Coated Negative Achromatic Doublet Lens are corrected for color and on-axis aberrations. These achromatic doublet lens, consisting of two optical elements cemented together, are commonly used as Barlow lenses to extend focal lengths. Broadband AR Coated Negative Achromatic doublet Lens are available in various diameter sizes and VIS 0° or VIS-NIR coating options. China Star Optics can provide Positive Achromatic doublet Lens and Negative Achromatic doublet Lens by two piece single lens (Doublet) or Achromatic triplet lens by three piece single lens (Triplet).

Blackening the edges of the achromatic doublet lens will reduce stray-light and increase the signal-to-noise ratio in an optical system.You'll see an improvement in your application. 

Other single optical Spherical Lens are available upon request. Such as Plano-Convex Spherical Lens,Plano-Concave Spherical Lens,Double-Convex Spherical Lens,double-concave spherical lens,Meniscus Spherical Lens,special spherical lens,ball lens,sphere lens etc.
