Specific parameters

Optical plano-convex lens



Plano-convex lenses are positive focal length elements that have one spherical surface and one flat surface. These lenses are designed for infinite conjugate (parallel light) use or simple imaging in non-critical applications. These optic lenses are ideal for all-purpose focusing elements.

Product Description


Plano-Convex Lenses are Optical Lenses with a positive focal length. Plano-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. PCX Lenses have one convex surface. For maximum efficiency, the second, plano (flat) surface should face the desired focal plane. Plano-Convex lenses are commonly used in a wide range of applications or industries.



A plano-convex lens is a convergent lens with one flat surface and one convex surface. It focuses parallel light rays to a positive focal point, to form real images that can be manipulated using spatial filters. The asymmetry of plano-convex lenses reduces spherical aberration in applications where the image and object lie at unequal distances from the lens.

The maximum sharp focus is achieved when the curved portion of the lens is oriented toward the object. Plano-convex lenses are used for applying focus to an optical system, and collimating diverging light beams.

Plano-convex lenses have positive focal lengths, and an orientation critical to the image quality. Low spherical aberration is obtained if the lens is orientated such that the collimated beam enters or exits the curved surface, thereby making the plano side face towards the point source or focus.
