Triplet Achromatic Lenses are designed for 1:1 conjugate ratios and utilize symmetry to correct for aberrations. They are made from a low index center element cemented between two identical high index outer elements. Each lens is edged down to f-numbers with reasonable aberration correction at increased fields. Some medical instrument will use micro triplet lenses.

We can provide custom achromatic lenses, both as doublets and triplets, manufactured to your specific requirements. Our typical manufacturing capabilities can be found below, and a range of glass types are available including Schott (and equivalent) materials.
