Positive Achromatic Doublet Lens and Negative Achromatic doublet Lens by two piece single lens (Achromatic Doublet Lens) or three piece single lens (Achromatic Triplet lens) are available. Achromatic doublet lens has significantly better optical performance than singlet Spherical Lens in visible imaging and laser beam manipulation applications.It consists of a positive low-index Crown Glass lens element cemented to a negative high-index Flint Glass lens element. The elements are chosen so as to cancel chromatic aberration at two well-separated wavelengths, usually in the blue and red region of the spectrum. Focal length is constant at those two wavelengths and focal length shifts are virtually eliminated across the visible wavelengths. One frequent use is to achieve diffraction limited focusing of a laser beam. Negative Achromatic doublet lens is typically used when there is a need to eliminate chromatic aberration. In addition to reducing chromatic aberration at the design wavelengths, spherical aberration and coma are greatly reduced. We always make our Optical Achromatic Lens as precise specifications and tolerances for uncompromising image quality upon customer's requirement. Blackening the edges of the achromatic doublet lens will reduce stray-light and increase the singal-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. Achromatic doublet lens Specification of our achromatic doublet lens as follow:
