Plano Convex Lens
Lens
>>> Plano Convex Lens
These lenses have positive focus length. They are most suitable in
applications where one
conjugate is more than five times the other, e.g. sensor
application or for use with near collimated light. For application in
which both conjugates are on the same side of the lens, it can be used as an
add-on lens to increase the numerical aperture.
