  The Durham Microoptics Programme was established to develop key components to
be used for integral field spectrographs for upcoming instrumentation projects,
focussing on currently existing telescopes as well as on the next generation of
ELTs. These activities include monolithic multi-optics machining and grinding,
optical surface improvement using various post polishing techniques and
replication of micro-optical components. While these developments have mostly
slicer-type IFUs in mind, also new types of microlens arrays are in development
for fiber based high contrast IFU systems.
