Spherical lens are used for beam focusing and beam collimation. Our precision lens start with optical materials designed for high transmittance over the desired spectral range. Careful consideration is given to create lens shapes with high surface accuracy and surface quality. Spherical Lenses can be classified as Plano concave lens(PCV lens), Plano convex lens(PCX lens), Double concave lens(DCV lens), Double convex lens(DCX lens), Mennicus lens, Achromatic lens(Doublet lens), Rod lens, Ball lens and Core lens according to different applications.  In UNI OPTICS, the material of BK7, Fused silica, CaF2 and MgF2 as standard. Other materials are available upon requirement.
