BK7 Optical Plano-Concave Lens for Optical Display Systems

Features:
Diverges incident light, Reduce spherical aberation, High Precision Dimension Control, Optional Substrate Material.

Applications:
Beam expansion systems, Light projection systems, Optical Display Systems, Projection Optical Systems, Imaging Optical Systems, Laser Measurement Systems, etc.

Description:
Plano-Concave (PCV) or negative focal length lenses have a flat surface on one side and a spherical surface on the other. They are used to expand beams or to increase focal lengths in optical systems or other similar applications.

Plano - concave lenses are negative spherical lenses with one concave surface and one flat surface. These lenses can be used to expand light or to increase the focal length of an optical system.

Plano-concave lenses are available either uncoated or with single layer AR coating. Broadband multi-layer antireflection coating can be done on custom basis.

Simple shape lenses for spreading the collimated laser beam.
These are available for expanding the beam diameter or in combination with convex, expanding the irradiation area of illumination light.
