Concave lenses

What are you looking for in Stock?

Concave lenses, are a simple lens with one spherical face and one flat plano face. Because the spherical face is concave the lens has a negative focal length, allowing the part to increase the divergence of convergent light. Concave lenses can be used to balance out the spherical aberrations caused by other lenses. This makes concave lenses very useful for controlling laser beams.

Being a simple lens, concave lenses have a broad range of applications including, but not limited to, focussing and control of laser beams, moderate quality imaging and other optical instruments. In a multi-element optical system they reduce the power of the system. Used on their own they form a diverging cone or virtual image. A typical use for concave lenses would be in a beam expander.
