High-precision towers for support of an optoelectronic detector

This paper describes the construction of an high precision towers for support an optoelectronical detector during fabrication. For fabrication of an optoelectronical detector is necessary a special room with a special environment. After assembling the frame of detector must be in plane, in range of ± 10 μm. In this condition, we are need special condition for measurement the mechanical pieces and the assemblies. Special construction of detector request that the towers must be very precise, mechanical assemblies that can be replaced very easy will compose them. With this restriction the towers are builds from three parts: inferior, intermediary and superior.
