Product Description

 

BRD Optical is one of professional optical mirror manufacturers. We provide Plano Concave Cylindrical Lens, Plano Convex Cylindrical Lens, precision optics and so on. Want to know about optical application? Please conatct us.

 

Plano concave lens bend parallel input rays so they diverge from one another on the output side of the lens and hence have a negative focal length. The spherical aberration of the plane concave lens is negative and can be used to balance aberrations created by other lenses. Similar to the plano concave lens, the curvature surface usually faces the largest object distance or the infinite conjugate to minimize spherical aberration. We also offer the two plano concave lens of glass of refractive index 1.5.
