| Triplet Achromats |
|
Specifically designed for 1:1 conjugate ratios, Steinheil triplets
are ideal for use in relay systems. Utilizing symmetry to correct
for aberrations, Steinheils are made from a low index center
element cemented between two identical high index outer elements.
In addition, each lens is edged down to f-numbers with reasonable
aberration correction at increased fields. Decreased diameters
allow lens mounting in a smaller space than traditional Steinheil
designs permit. BaSF1; nd = 1.626. AR Coated, 1/4 wave MgF2.
