Avantier offers versatile aspheric lenses with anti-reflection coatings or uncoated options, in glass, crystalline, or plastic substrates. Utilizing cutting-edge grinding and polishing equipment, such as computer-controlled precision devices and magneto-rheological finishing (MRF) technology, we guarantee optimized surface quality for your specific application.
Aspheric lenses enable thinner and lighter lenses compared to traditional spherical lenses needing multiple elements to achieve similar image quality. This is beneficial for portable devices like cameras.
Customizing the curvature of aspheric lenses allows engineers to optimize optical systems for better performance, reduced size and complexity, and potentially lower cost.
We offer custom aspheric lenses in various sizes, materials (glass, crystal, plastic, and etc.), and with different surface quality specifications upon customer's request.
