High quality optical grade glass BK7 concave convex Meniscus lens
Product Description
Meniscus lens
Meniscus lens is a lens which has two spherical curved surfaces, convex on one side and concave on the other side.
It is thicker at the center than at the edges. The lens provides a smaller beam diameter in order to reduce the beam waste and spherical aberration. When a meniscus lens is combined with another lens, the focal length is shortened and the numerical aperture of the system is increased. This reduces the image distortion and increases image resolution.

Detailed Images
Meniscus Lens can increase the NA of the system while only adding slightly to 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.
We can customized all kinds of optical lens and prisms according to the drawing and your request.
