Optical Lenses, optical lens

Optical lenses is the most advantage product of A-Star’s optics.
A-Star got a complete set of optical Lenses Measurement System:
Strictly control the Flatness, Radius, Focal, Center error and S/D.
ZYGO Interferometer and AK-40 Interferometer 100% inspect the surface PV & IRR.
We offer optical lenses including conical (axicons) lens, plano convex lenses, biconvex, plano concave lens, biconcave, cylindrical lenses.


Plano Convex Lenses

Plano-convex Lenses present a curvecd interface and a planar interface. Thay are for instance the microlenses situated on top of a wafer, and also encountered in macroscopic optical systems

Plano-Concave Lens

Plano concave Lenses have one concave surface. It has negative focal length. It is often used to expand light or to increase focal length in existing systems.

Double-Convex Lens

Two refracting surfaces of optical lens are both spherical or one is spherical and the other is flat. Astar can supply standard and high-precision spherical lens in a variety of shapes, sizes, focal lengths on a wide spectrum.

Double-Concave Lens

Plano-concave cylindrical lenses provide uni-axial negative imaging for anamorphic beam expansion and a wide range of applications. These lenses are manufactured from UV transmitting Fused Silica and are supplied uncoated. Anti-reflection coatings are available as listed earlier in this section.

Meniscus Lens

Meniscus Lens can increase the NA of the system while only adding slightly to the total spherical aberrations. The Negative Meniscus Lens is used to increase the focal length of another lens while maintaining the angular resolution of the optical assembly.

Achromatic Double Lens

An achromatic lens or achromat is a lens that is designed to limit the effects of chromatic andspherical aberration. Achromatic lenses are corrected to bring two wavelengths (typically red and blue) into focus in the same plane.

Cylindrical Lens

Cylindrical lenses are used to correct astigmatism in the eye and in rangefinders, to produce astigmatism, trenching a point of light into a line, they are widely used in bar code scanning, projection optics systems, laser measurement systems and holography.
