Plano concave lens is a simple lens with one spherical face and one flat face, it has a negative focal length, allowing the part to increase the divergence of convergent light. Plano concave lenses can be used to balance out the spherical aberrations caused by other lenses. Concave lenses have a broad range of applications including, focusing and control of laser beams, imaging, and other optical instruments. 
Hangzhou Shalom EO stocks a series of N-BK7 plano-concave lenses with various diameters, focal lengths, and coatings, and the custom lens with other specifications are also available upon request.
