Plano-concave Lenses
Plano-concave
lenses are used to introduce negative power into an optical system.
They are
supplied either uncoated or with a single layer anti-reflection coating suitable
for the ultra-violet (200-350 nm), the visible (350 - 600 nm) or the near
infra-red (600 – 1200 nm).
A
wide range of focal lengths and diameters are available (see datasheet for
common sizes and focal lengths).
Please ask for sizes and focal lengths required as we can supply a wide
selection of these lenses.
