Aspheric lens, the radius of curvature varies with the center axis, to improve optical quality, reduce optical elements, reduce the design cost. Aspherical lens has unique advantages over spherical lens, so it has been widely used in optical instrument, image and optoelectronic industry, such as digital camera, CD player，bar code scanners, night vision devices, infrared thermal imagerslaser diode collimation， high-end microscopic instrument etc.

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 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.
