These lenses are symmetrical with equal radii on both sides. The biconcave lenses are often used to expand light beams or to increase focal lengths in optical systems, and are normally used in combination with other lenses. Among the many devices utilising biconcave lenses are laser beam expanders,... [See More]

- Center Thickness: 1.7 to 4.8
from ECOPTIK (CHANGCHUN) LTD
A cylindrical lens is typically used to focus, condense or expand incoming light. A cylindrical lens has one cylindrical surface, causing light to be focused in a single dimension or axis. It can also be used to expand the output of a laser diode into a symmetrical beam. Cylindrical lenses are... [See More]

from EKSMA OPTICS
These simplest form lenses have flat surface on one side and spherical surface on the other. They are widely used in telescopes, microscopes, collimators, optical transceivers, magnifiers, condenser systems and eyepieces. Plano convex lens made of BK7, UV FS (UV grade Fused Silica), CaF2 (Calcium... [See More]

from ECOPTIK (CHANGCHUN) LTD
Meniscus Cylindrical 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. This lens shape is best used... [See More]
