Meniscus lenses form the largest and most popular part of our product range. Optimised meniscus designs Manufactured in high quantities to keep costs low. Quality matches or exceeds any other supplier.

Product Introduction

Positive meniscus lenses may be used to increase the numerical aperture of a positive lens assembly without an undue increase in the aberrations. For the case of a lens of thickness tc  in air, and surfaces with radii of curvature R1 and R2, the effective focal length f is given by:

where n is the refractive index of the lens medium. The quantity 1/f is also known as the optical power of the lens. The the back focal distance:

In the sign convention used here, the value of R1 will be positive if the first lens surface is convex, and negative if it is concave. The value of R2 is positive if the second surface is concave, and negative if convex. Note that sign conventions vary between different authors, which results in different forms of these equations depending on the convention used.

Meniscus lenses form the largest and most popular part of our product range.
