A Minimax Fitting Algorithm for Ultra-Precision Aspheric Surfaces
Aspheric lenses show significant superiority over traditional spherical ones. The peak-to-valley form deviation is an important criterion for surface qualities of optical lenses. The peak-to-valley errors obtained using traditional methods are usually greater than the actual values, as a consequence causing unnecessary rejections. In this paper the form errors of aspheric surfaces are evaluated...
متن کاملPrecision machining and measurement of micro aspheric molds
Abstract –Demands of micro aspheric optical components such as lenses and mirrors are increasing for installing to the digital devices such as DVD, Digital camera, mobile phone and virtual reality system. As the devices become to be more compact and complicated, the molds shapes of lens and mirrors would become smaller and complicated, and then would become more difficult to be machined and mea...
متن کاملUltra-precision: enabling our future.
This paper provides a perspective on the development of ultra-precision technologies: What drove their evolution and what do they now promise for the future as we face the consequences of consumption of the Earth's finite resources? Improved application of measurement is introduced as a major enabler of mass production, and its resultant impact on wealth generation is considered. This paper ide...
متن کاملAdvances in Ultra Precision Manufacturing
In the past many qualified technologies have been established for the manufacture of optical, precision and micro parts as well as precision structured surfaces. In this field mechanical machining processes, like diamond machining, play a dominant role. Novel mechanical manufacturing processes, further development of ultra precision machine tools and the precision machining of challenging mater...
متن کاملUltra-precision engineering: from physics to manufacturing.
Sir Christopher Wren is widely acknowledged as a key individual in the formation of the Royal Society, a society initially advocated ‘for the promotion of physicomathematical experimental learning’. Many people would not be surprised to learn that England’s most famous architect was a driving force behind the Royal Society. But most people would not know that Wren was at that time an astronomer...
