Paper Abstract

In many applications of micro optics, eg Fibre optic sensors or intergrated optics discrete components have to be assembled precisely and in an environmentally stable form. Several chemical companies have developed dental restorative materials which have many desirable features for optical assembly. ICI's Light Curing Resin family in particular is endowed with 1 Visible light cure - no hazards due to UV. 2 Rapid cure on command. Ideal for precision assembly. 3 Low shrinkage on cure. 4 Cure to 10 mm depth in one minute. 5 Cure through 4 mm of white alumina ceramic in one minute. 6 High refractive index for integrated optics applications. 7 Refractive index 1.52 for fibre splicing or lens assembly. 8 Wide range of viscosities for different assembly processes eg fibre bundle termination or laser Diode receptacles. 9 Low thermal expansion coefficent in reinforced grades. The paper will discuss how these properties are obtained and their uses in the exciting field of microptics assembly. Finally an interesting temperature sensor based upon a glass filed resin will be described to illustrate the range of properties which can be combined.
