+1 Cemented Achromatic Doublets
Achromatic lenses consist of two optical components cemented together to form an achromatic doubled, which is computer optimized to correct for on-axis spherical and chromatic aberrations. | | +2 Cemented Achromatic Triplets
An achromatic triplet is the simplest lens that corrects all primary chromatic aberrations. These triplets consist of a low-index center element cemented between two identical high-index outer elements and feature good on-axis and off-axis performance. | | | | +3 Achromatic Doublet Pairs
Worldhawk offers Matched Achromatic Pairs for use in the visible or NIR spectral range. Matched Achromatic Pairs are ideal for image relay, NA conversion, or image magnification. | | +4 Air-Spaced Achromatic Doublets
Worldhawk' selection of air-spaced achromatic doublets offer diffraction-limited spot size, superior aberration correction, and higher damage thresholds than traditional cemented doublets. They have been designed for use across broad wavelength ranges with minimal aberrations. | | | | +5 Negative Achromatic Lenses
Consisting of two optical elements cemented together, negative achromats are corrected for color and on-axis aberrations. Used predominantly as Barlow lenses to extend focal lengths, they are often combined with positive achromatic mirror systems and imaging lenses. | |
