精密研磨非球面レンズは、CNC研磨などの超精密加工技術を用いてガラス素材から直接材料を除去し、非球面曲率を形成する光学部品です。その真価は、極めて高い表面精度（λ/40 RMS未満）を実現していることにあり、特に厳しい画質要件が求められる用途に適しています。
Up to λ/40 RMS (~15 nm) or even higher.
Processes such as MRF and IBP can achieve ultra-smooth surfaces, avoiding scattering losses and eliminating subsurface damage that may affect the laser damage threshold.
For lenses with diameters ranging from tens of millimeters to several meters, or for hard and brittle materials that cannot be machined using molding (such as SiC), precision polishing is the only option.
Because it does not require expensive molds, precision polishing is ideal for small-batch, diverse prototyping and special customization needs.
