A-Star photonics inc offers a wide range of optical components including mirrors, lenses, laser windows, optical filters, prisms, polarizing optics, UV and IR Optics.
Choose A-Star optical components for a wide variety of applications including wavelength division multiplexing and optical sensors.
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 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.
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.
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 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.
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 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.
CaF2 Window (Calcium Fluoride Window) is the most advantage product from A-Star’s Plano Workshop. Fluorides are usually toxic to humans, however CaF2 is considered relatively harmless due to its extreme insolubility.
MgF2 Windows(Magnesium Fluoride) is another advantage product of A-Star Photonics. MgF2 material is very difficult to polish due to its soft, A-Star has the stable producing line for several years. We make MgF2 Windows more than 10000pcs each month.
