Positive meniscus lenses and Negative meniscus lenses

Positive meniscus lenses is convex-concave lens thicker at the center than at the edges. They are used to minimize spherical aberration. When used in combination with another lens, it’s will shorten the focal length, and increase the NA of system.

1. Frequently Used for Beam Focusing Applications
2. Minimizes the Increase in Spherical Aberrations for Multi-Element Systems

Negative meniscus lenses is convex-concave lens thinner at the center than edges. They increase the divergence of the beam without introducing any significant spherical aberration. When used in combination with another lens, they will increase the focal length, and decrease the NA of the system.

1. Frequently Used for Beam Expanding Applications
2. Minimizes the Increase in Spherical Aberrations for Multi-Element Systems
