“…The atoms present in the workpiece receives the energy transferred from the collided ions at the top surface as shown in figure 22. If the energy level absorbed is insufficient by the workpiece atoms to overcome the lattice binding energy, then the absorbed energy is released in the form of phonons [179].…”

Freeform optics has become the most prominent element of the optics industry. Advanced freeform optical designs supplementary to ultra-precision manufacturing and metrology techniques have upgraded the lifestyle, thinking, and observing power of existing humans. Imaginations related to space explorations, portability, accessibility have also witnessed sensible in today’s time with freeform optics. Present-day design methods and fabrications techniques applicable in the development of freeform optics and the market requirements are focussed and explained with the help of traditional and non-traditional optical applications. Over the years, significant research is performed in the emerging field of freeform optics, but no standards are established yet in terms of tolerances and definitions. We critically review the optical design methods for freeform optics considering the image forming and non-image forming applications. Numerous subtractive manufacturing technologies including figure correction methods and metrology have been developed to fabricate extreme modern freeform optics to satisfy the demands of various applications such as space, astronomy, earth science, defence, biomedical, material processing, surveillance, and many more. We described a variety of advanced technologies in manufacturing and metrology for novel freeform optics. Next, we also covered the manufacturing-oriented design scheme for advanced optics. We conclude this review with an outlook on the future of freeform optics design, manufacturing and metrology.

“…Одним из перспективных инструментов модификации поверхности являются пучки газовых кластерных ионов. Показано, что благодаря нелинейным эффектам коллективного взаимодействия падающих кластеров с твердым телом и возможности независимо регулировать их размеры и кинетическую энергию можно сглаживать поверхности различных материалов с минимальным повреждением структуры обрабатываемого материала [4][5][6].…”

It is demonstrated that a argon cluster ion beam can be used for the finishing treatment of ultrasmooth surfaces (with initial root-mean-square roughness below 0.3 nm) of potassium titanyl phosphate single crystals. Analysis of the power spectral density function of surface roughness showed that cluster-ion irradiation leads to removal of residual chemical contaminations from the subsurface layer and produces additional smoothing of the crystal surface in a broad range of spatial frequencies (ν = 0.2–100 μm^–1).
