BK7 cylindrical lens positive meniscus lens
Meniscus cylindrical lens is a lens that one surface is convex shape, another surface is concave with cylindricalshape, The Negative Meniscus Lenses are a convex-concave lens,
but is thinner at the center than at the edges. Otherwise description is similar to Plano Concave lenses.
its role is making beam converging or diverging on a plane, and that beam does’t work for the perpendicular plane(cylindrical axis) with it of the appropriate wavelength.
When used to form a positive lens assembly, the Positive Meniscus lens can increase the NA of the system while
decreasing the total spherical aberrations. The Negative Meniscus lens is used to increase the focal length of another lens
while maintaining the angular resolution of the optical assembly. This lens shape is best used when one conjugate is relatively far from the lens
