Spectral system (acronym SPECTECH) is designed to meet the following basics: a) to assure measuring tiny optical single lens in a standard configuration; b) configured for reflected or transmitted beam light; c) configured by user off line to monitor manufacturing or mounting optical components; d) to be flexible to be equipped with more than one spectral detector. Initially, it is equipped with two spectral detectors, but in short time to be able to use more than two. e) configured as process spectrophotometer (continuously) to monitor manufacturing or mounting optical components; f) to be updated or upgraded to meet other necessities. SPECTECH system is a modular one, allowing spectral determinations in a wide range of spectrum (385-1100 nm) and with two detectors UV-VIS (190-1100) and NIR (1000-1700nm) the domain can be wider, covering spectrum from 190 to 1700 nm.

This paper explains and demonstrates how to use rapid prototyping to make human sight better compensate by aerial devices in according to optical prescription and facial profile. The paper show a way to improve or match the aerial devices (aka frames) with individual facial characteristics and deliver a customized solution to fit on face and keep device in place for general comfort and better sight. Examples used in this material are realized by authors themselves
