cylindrical lens is used to correct astigmatism in theeye,and,in rangefinders, to produce astigmatism,stretching apoint oflight into a line.they are available ineither planoconcaveorplanoconvex configurations. plano-concavecylindricallenses havea negative focal length and are used forimage reductionor tospread light. plano-convex cylindrical lenseshave a positivefocallength,whichmakes them ideal for collectingand focusinglightfor many imaging applications.
plano-convex cylindricallens,plano-concavecylindricallens,bi-convex cylindricallens,bi-concavecylindricallens,meniscus cylindrical lens,longcylindricallens,specialcylindrical lens etc..
