Product Description

Optical Lenses are optical components designed to focus or diverge light, widely applicated from microscopy to laser processing. A Plano-Convex or Double-Convex lens causes light to focus to a point, while a Plano-Concave or Double-Concave lens diverges the light which traveling through the lens. Achromatic Lenses are ideal for correcting color, aspheric lenses are designed to correct spherical aberration.Ge, Si, or ZnSe lenses are suited for transmitting the Infrared (IR) spectrum, fused silica is well suited for the Ultraviolet (UV).

Aspheric Lenses

Precision Aspheric Lenses are designed to focus light while eliminating spherical aberration from divergent light sources in applications including focusing the output of a laser diode. Aspheric lenses can increase the numerical aperture of a lens while minimizing system aberrations. Aspheric lenses may also reduce the number of elements needed in a multi-element system. Aspheric lenses can reduce overall system weight while providing advantages such as increasing throughput or simplifying assembly.
