A lens is an optical device with perfect or approximate axial-symmetry which transmits and refracts light,concentrating or diverging the beam.A simple lens is a lens consisting of a single opticalelement.A compound lens is an array of simple lenses (elements) with a common axis;the use of multiple elements allows more opticalaberrations to be corrected than is possible with a single element. We offer following lenses A. BK7 Simple Lenses B. Fused Silica Simple Lenses C. Meniscus Lenses D. Doublet Lenses E. Cylindrical Lenses
