Plano concave lens Plano-concave lenses have negative focal lengths and can be used to diverge collimated beams. In this case, the curved surface of the lens should face the source to minimize spherical aberration. In addition, they can be employed to offset the effects of spherical aberration caused by other lenses in an optical system. Yutai Optics can supply high quality plano concave lens in 1" 1.5" or 2" diameter as request. Also it is available to arrange hole, notch and cut as request.
