With the rapid development of optical electromechanical micro-systems,it is widely used in optical communications,photoelectric sensors,micro-optoelectronic systems and so on.The optical system is also urgently needed to be miniaturized,especially the miniaturization of optical components.As one of the most basic and important components of optical system,lens is urgently needed to be miniaturized.Therefore,the fabrication of compact and low-cost aspheric microlens has become one of the focuses in the field of current research.By use of optic micro-lens molded on needing position manufacturing technology made of aspheric microlenses,has the advantages of high precision,with the optical axis,good surface finish and so on.The manufacturing technology mainly adopts UV material manufacturing micro lens.However,there are many kinds of UV radiation curing photoinitiator,their maximum absorption peak is very different,and the range of sensitization is also very different.At present,UV lasers in the near ultraviolet range(300-400nm)have only a light wavelength of 355 nm,not only the high cost,but also cannot meet in the production of micro lens in different UV radiation curing light induced spectral agent needed.In view of the above problems,this paper presents a multi-beam integrated UV light source system to solve the "bottleneck" problem,and launched the following research.This paper presents a multi-wavelength near-ultraviolet light source system.The system achieves the emission of multi-spectral ultraviolet light by controlling the film thickness and the number of layers of the interference filter.And through a combination of multiple xenon lamp condenser array to achieve the launch of high-energy,high-brightness ultraviolet light,and then instead of UV lasers.Aiming at the proposed a multi-wavelength near-ultraviolet light source system,a concrete scheme is given the specific technical scheme is given.The xenon concentrator system,the multi-channel concentrator unit,the Shift light implement,the mixer implement and the combined filter are theoretically calculated,and the overall design of UV light source.How to improve the concentrator efficiency of xenon concentrator system and multi-channel xenon concentrator system is studied.Related technologies have been granted the national utility model patent license.Based on the practical realization of a multi-wavelength near-ultraviolet light source system,the xenon lamp is the core part of the UV light source system.The design scheme of the xenon lamp power supply is completed and the circuit design of the xenon lamp power part is carried out.The realization of the circuit design,making a multi-wavelength near-ultraviolet light source system technology solutions can be achieved,and made in kind.The correctness of the design of the circuit is proved by the parameter calculation.At the same time,the saber software is used to simulate the driving circuit and the improved drive circuit of the half-bridge DC converter.The feasibility of the improved circuit is proved by simulation waveform.To meet the design of the circuit needs of the voltage,for the future study laid the theoretical basis.
