They spread light rays apart, giving the impression that they are coming from a virtual focus.
Used for correct divergence, enlarge a beam or stabilize an optical projection.
Biconcave lenses scatter the light, creating a virtual focus. They are used for widen or homogenize a beam, or for correct convergence of an optical system.
Particularly used in laser systems and projection devices.
With one flat and one concave face, plano-concave lenses produce a moderate light beam divergence. They are used to adjust the divergence of a laser, correct a wavefront or control the projection of a light beam.
These lenses have a convex and a concave face, with a dominant curvature on the concave side.
They trigger a divergence of light rays incidents for correct certain optical aberrations, widen light beams or adjust the focus of a system.
Divergent meniscus lenses are used in a variety of optical systems to control divergence, improve imaging and optimize performance in instrumentation and metrology.
