Reasonable Plano Convex Lens BK7 40mm Diameter 120mm Focal Length 400 - 700nm

S-SLB-40-120PM

This lower cost product offering of Plano Convex Lenses has only minimal reduction in quality and is perfect for most applications. It can be used in an optical systems such as observation or lighting applications when the higher surface quality Plano Convex Lens (SLB-P) is not required.
◦It has the same specification of Plano Convex Lens (SLB-P) except the surface quality and is ideal for experiments and applications where high-precision is not required.
◦There are two types of lens offer, a Plano convex lens with low spherical aberration and a biconvex lens that is used to shorten the focal length.
◦In addition to uncoated products, there are three types of anti-reflection coating for visible, near-infrared, and infrared.
