Plano Concave Lenses (PCV) have one concave surface and a negative focal length, ideal for beam expansion, collimated beam divergence and focal length adjustment across optical systems. As high-precision optical components, they are widely used for light projection in laser optics, medical imaging, microscopy and fiber optics. To ensure optimal performance, install the lenses with the flat plano surface facing the focal plane.
