Aspherical Lens, the radius of curvature varies with the central axis. To improve optical quality, reduce optical elements, lower design cost.
Basic Technical Parameters
Tolerance of Dimension: ±0.05mm
Surface Accuracy: 1/2λ，λ/4 per φ25.4mm
Centration：≥1′
Surface Quality: 60-40, 40-20, 20-10，10-5
Chamfer: 0.2-0.3mm×45°
Clear Aperture： >90%
Polish： High-precision Polish on Both Surfaces
Aspheric lens has unique advantages over spherical lens, therefore, it is widely used in optical instrument, image and optoelectronic industry, such as digital cameras, car lenses, and high-end micrometers.
