Product Family Description

TECHSPEC® Steinheil Triplet Achromatic Lenses are designed for 1:1 conjugate ratios and utilize symmetry to correct for aberrations. Steinheils 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. TECHSPEC® Steinheil Triplet Achromatic Lenses feature small diameters that allow for mounting in smaller spaces compared to traditional Steinheil lens designs. Steinheil Triplets are ideal for use in relay systems.
