Bi-convex Lenses
Bi-convex
lenses are often used as image relay or field lenses. Being symmetrical, they
are close to the best form working at 1:1 magnification.
They are therefore ideal for image relay purposes.
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.
