Cemented Lens
Cemented lenses, also called achromatic lenses, bond two lens elements and greatly improve polychromatic white-light imaging over a single lens. Elements made from different materials correct glass dispersion. Eliminating chromatic aberration enables wide use in multicolor illumination and imaging with improved cost efficiency. Coatings are available as required.
