Product Description

Optical lenses can be made in many shapes and may be comprised of a single element or form constituent parts of a multi-element compound lens system. They are used to focus light and images, produce magnification, correct optical aberrations and for projection, mainly controlling the focus or divergence light used in instrumentation, microscopy and laser applications.

A lens is a sphere that has two sides cut from it and is used for optical purposes. The sides can be cut in three different ways: concave, convex, or plane. Mixing and matching these different cuts results in different types of lenses that can be used for different applications. These applications include but are not limited to:

Microscopes
Telescopes
Eyeglasses

Any specification of convex or concave lens can be produced according to required transmission and material, to a specific focal length.
 

Convex lenses bulge outward from the center and converge light rays parallel to the optical axis to a focal point beyond the lens. Therefore, they may also be referred to as positive or converging lenses. The focal point is the point where the collimated light rays converge and come into focus.

Concave lenses curve inward from the center and diverge light rays parallel to the optical axis from a focal point behind the lens. Therefore, they may also be referred to as negative or diverging lenses. The focal point is the point where the collimated light rays appear to diverge from after passing through the lens.
