Most of our spherical optics are customized. We produce both small quantities and large volumes at competitive prices. 
Spherical lenses are optical components with surfaces that have a constant radius of curvature. Spherical lenses are typically used for focusing, collimating, or expanding incoming light.
As a leading optics manufacturer, MLOPTIC offers a broad range of precision-grade spherical elements. We have a variety of unique and proprietary manufacturing technologies including grinding, honing, die sinking, and etching. We also can exchange design data with you during development.

PLANO-CONVEX LENSES
Plano-convex lenses have one plane surface and one convex surface. These lenses have positive focal lengths. When producing real images at infinite conjugates, aberrations are minimized when the convex surface is facing the object.
PLANO-CONCAVE LENSES
Plano-concave lenses have one plane surface and one concave surface. They are primarily used to increase focal lengths in existing systems. They are a more suitable choice than the equivalent equi-concave lens if the magnification lies in the range of <-5 to >0.2.
MENISCUS LENSES
Meniscus lenses are lenses with one convex surface and one concave surface. Positive meniscus lenses are used to shorten the focal length of a doublet or a plano-convex lens already working at an infinite conjugate.
BALL LENSES
Ball lenses come in various sizes and are made of optical glass. They provide high coupling efficiency when used with fiber optics and can be put in contact with the end of the fiber.
CONICAL LENSES
Conical lenses have a conic surface. These components are designed for use in a variety of laser and imaging applications with standard sizes ranging from 3mm to 10mm. Cone Lenses can be used for 360-degree illumination and imaging applications. They are most commonly used in tandem with other lenses. Coated and uncoated versions are available to meet various applications. Other specifications are available upon request.
ROD LENSES
These components are designed for use in a variety of laser and imaging applications with standard sizes ranging from 2mm to 10mm. Collimated light passing through the diameter of the rod will be focused into a straight line. Their optical performance is similar to a cylinder lens. Other specifications are available upon request.
ACHROMATIC LENSES
Achromatic lenses consist of two or more elements that have been corrected for chromatic aberration with respect to two selected wavelengths. This is also known as an ‘achromat.’ Achromatic Doublets are made of two different glasses, crown, and flint. They are designed to perform over the entire visible spectrum with spherical and chromatic aberrations corrected to near diffraction-limited performance. Their ability to produce sharper images is superior to that of single element lens systems
Achromatic Triplets are specifically designed for a 1:1 conjugate ratio. They are ideal for use in relay systems. Aberrations are corrected automatically through the application of the symmetrical principle.
