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.
These lenses can be adapted by applying specific surface treatments and optical coatings to adjust their properties (transmission, reflection, resistance, filtering) to meet specific technical constraints and optical performance requirements.
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.
