We present a finite-element method to calculate 3-D surface profiles of refractive microlenses fabricated by melting-resist technology (reflow technique). The geometry of the microlenses can be arbitrary. Surface tension and gravity are taken into account. ...
Fused silica microlenses with low numerical apertures (NAs) were fabricated. The original photoresist element was realized by the melting resist technology and was transferred into fused silica by reactive ion etching. Low selectivity etching was applied t ...
Micro-optical systems based on refractive microlenses are investigated. These systems are integrated on a chemical chip. They focus an excitation beam into the detection volume (microliter or even submicroliter scale) and collect the emitted light from flu ...

An automated surface mounting assembly procedure has been developed for mounting miniaturized optical elements. It is based on a low cost universal holding device, free space optical interconnection, and on-line adjustment of the elements. It is characteri ...
This paper presents the fabrication of a microchemical chip for the detection of fluorescence species in microfluidics. The microfluidic network is wet-etched in a Borofloat 33 (Pyrex) glass wafer and sealed by means of a second wafer. Unlike other similar ...
