A common problem experienced in the opto-electronic industry is the need to rapidly and accurately fix time-consuming, optical alignments. Novel chemistry has allowed the development of a generation of positioning resins which combine very rapid cure ("command cure") to good depths with very low cure shrinkage. Interestingly, the cure is triggered by visible blue light, safer and faster than ultraviolet. The cured resins have good stability over a range of environments and show particularly good resistance to solvents. Typical properties of the resins are described with performance data relevant to opto-electronic applications. Applications where the system works to particular advantage are described.
