Plano Concave (PCV) Lens The lens has negative focal length, diverges collimated light and hence used for beam expansion. It has minimum spherical aberration for negative-infinite near-infinite conjugates, when concave surface faces the infinite conjugate. A convergent beam incidmore...
Diameter Tolerance: : +0.2 mm up to diameter 100mm(+0.5mm for diameter>100mm)
Center Thickness Tolerance: : +0.2mm
Diameter Range: : 5 mm to 300mm
Double Concave (DCV) Lens The lens has negative focal length, diverges collimated light and hence used for beam expansion. It has minimum spherical aberration for negative-infinite near-infinite conjugates, when concave surface faces the infinite conjugate.A convergent beam incidmore...
