Replication of micro optical components by UV-molding process

Abstract

An experimental method is presented to maximize the replication quality of UV-molded micro-optical components. It is important to maximize the replication quality, because one can obtain the replicated micro-optical components with desired properties by accurate control of the shape. In the present study, a simple technique to avoid micro-air bubbles was first suggested. The effects of the UV-curing dose and the compression pressure on the replication quality of UVmolded structure were examined experimentally. Finally, as a practical application of the process design method, microlens arrays with diameters between 8µm and 230µm were fabricated by the present method, and the replication quality and the optical properties of the replicated micro-lens were measured and analyzed.

Realizing high photovoltaic efficiency with parallel multijunction solar cells based on spectrum-splitting and -concentrating diffractive optical element

“…Since the DOE is a surfacerelief structure on the substrate, once a hard mold with a complementary structure is manufactured, mass production of the DOEs can be realized by replication technology. [27,43]…”

Design of optical path of pickup for small form factor optical disk drive

“…In general, microlens and lens array can be produced using various methods such as photoresist reflow method, etching, lithography, laser ablation, microjet method, and molding (Kang and Moon 2001;Kim et al 2003;Moon et al 2002Moon et al , 2003. The molding process, which includes injection molding, compression molding, hot embossing and UV molding, is regarded as the most suitable process to achieve high repeatability and high mass production capacity.…”

Design and fabrication of micro imaging lens for biomedical applications

“…Because of several reasons such as complex numbering system and use of a look-up chart, 1951 resolution test chart is not used widely and modem charts such as T21 and T22 as shown in figure 7-13 are used widely to determine the resolution power of imaging systems.The actual lateral resolution of the optic system can be determined using table 7-1. The resolution is the size of the smallest pattern which the optical system is capable of imaging.The size of patterns on USAF test chart is determined by: Resolution = 2" (Group + 13: (a) USAF Resolution Test Chart -improved labeling T21 ; (b) USAF Resolution Test Chartimproved labeling T22[75]…”
