• Simplify Assembly and Minimize System Weight
• Eliminate Spherical Aberration
• Improve Resolution and System Performance
Spherical Aberration
A single asphere o ers the same amount of spherical aberration correction
that two or more spherical lenses can accomplish. Aspheres, by
their very nature, are without the spherical aberration that is inherent in
traditional Plano-Convex and Double-Convex spherical lenses. A single
asphere in a system design can signi cantly improve performance while
reducing element count.
