Lenses
Plano-convex, plano-concave, biconvex, biconcave, plano-convex cylindrical, plano-concave cylindrical lenses made of BK7, UVFS or CaF2 optical material. Focal lengths vary from -1000 to 5000 mm.

A compound lens is a collection of simple lenses of different shapes and is made of materials of different refractive indices, arranged one after the other with a common axis.
Lens kits contain 36 lenses made from UV grade fused silica. The kits are suitable for optics studies and research purposes where multiple focal length lenses may be required.
Lens kits contain 40 lenses made from BK7 optical glass. The kits are suitable for optics studies and research purposes where multiple focal length lenses may be required.

The axicons can be used to convert a parallel laser beam into a thick-walled hollow "pipe" of light or to produce an annular focus.
These simplest form lenses have flat surface on one side and spherical surface on the other. They are made of BK7.

These simplest form lenses have flat surface on one side and spherical surface on the other. They are made of CaF2.
Biconvex lenses, made of BK7, are all symmetrical. They are recommended for virtual imaging of real objects, and for positive conjugate ratios from 0.2 up to 5.

These lenses are thicker at the edge than in the centre and flat on one side. The plano-concave lenses are used to expand light beams or to increase focal lengths in optical systems.
The Biconcave Lenses are often used to expand light beams or to increase focal lengths in optical systems, and are normally used in combination with other lenses.
These lenses are used in laser scanners, spectroscopy, dye lasers, acousto-optics, optical processors and other similar applications.
