A-Star’s Plano concave cylindrical lenses
Cylindrical Lens
Cylindrical lenses focus or expand light in one axis only. They can be used to focus light into a thin line in optical metrology, laser scanning, spectroscopic, laser diode, acousto-optic, and optical processor applications. They can also be used to expand the output of a laser diode into a symmetrical beam.
A-Star also can offer Plano convex cylindrical lens,Plano concave Cylindrical Lens,Bi convex cylindrical Lens,Bi concave cylindrical lens,Menisus cylindrical.
