The micro lenses applying in the field for medical endoscope, available with:
plano-convex, plano-concave, Bi-Convex, Bi-concave, Achromatic lens, Meniscus lens
Achromatic Lenses for Rigid Endoscopes
Achromatic Lenses are used to minimize and eliminate chromatic aberration. The achromatic design also helps in minimizing spherical aberrations. Achromats are often designed by cementing two elements together.
