Aspherical Lens

Aspherical lenses feature a variable radius of curvature along the central optical axis, a unique structural design that enhances optical performance, reduces the number of required optical components, and lowers overall design costs.

Aspheric lenses use a single element design, which helps to minimize the number of lenses in the optical system. Aspheric lenses allow optical element designers to use fewer optical elements than traditional spherical elements to correct aberrations because the former provide them with more aberration correction than the latter can provide using multiple surfaces.

In the fields of laser medical treatment and laser processing, aspherical lenses can better control the shape and divergence of the beam, improve the uniformity and quality of the beam.

In the field of aerospace, aspheric lenses are used in space optical equipment such as satellites and telescopes to improve imaging accuracy and stability and adapt to extreme space environments.

AOS Optics customizes without coating and anti-reflection coating aspheric lens. Anti-reflection coatings include UVA, VIS, NIR, SWIR, IR1, and IR2. AOS can also provide aspherical lenses of various materials, among which zinc selenide is suitable for infrared band applications, and molded optical glass is suitable for cost-effective mass production.
