Negative Meniscus Lens

Two refracting surfaces of optical lens are both spherical or one is spherical and the other is flat.

Worldhawk can supply standard and high-precision spherical lens in a variety of shapes, sizes, focal lengths on a wide spectrum.

The structure of lens can be Plano-convex, Plano-concave, Bi-convex, Bi-concave, Meniscus. They are widely used in medical, industry, spaceflight andmilitary etc..

Convex Lenses are optical lenses with a positive focal length. 

Convex Lenses are ideal for light collimation or for focusing applications utilizing monochromatic illumination, in a range of industries including industrial, pharmaceutical, robotics, or defense.

Concave Lenses are optical lenses with a negative focal length. 
Concave Lenses are ideal for beam expansion, light projection, or for expanding an optical system’s focal length.
