Symmetric or Bi Concave Lens

Bi concave or plano-concave, lens.
a collimated beam of light passing through the lens is diverged (spread); the lens is thus called a negative or diverging lens. The beam after passing through the lens appears to be emanating from a particular point on the axis in front of the lens; the distance from this point to the lens is also known as the focal length.

Starna Bi concave lenses are available in custom batches from our in house manufacturing plant, in a range of materials and dimensions from 8mm to 300mm

Plano Concave Lens

Concave lenses are available to order as with the bi concave lenses see above.

Symmetric or Bi Convex Lens

Bi convex or plano convex lenses
a collimated or parallel beam of light travelling parallel to the lens axis and passing through the lens will be converged (or focused) to a spot on the axis, at a certain distance behind the lens (known as the focal length). In this case, the lens is called a positive or converging lens.
