25mm Fast Spinning and Stepping Filter Wheel
SUMMARY
The Cairn Optospin25 continues our long tradition in filter wheel design, dating back to the 1980s, but taking full advantage of the continuing developments in motor and control technology that have taken place since then. It builds on our tried and tested approach of mounting the motor directly within the hub of the filter wheel, in order to maintain a compact size (no motor bulge!) and to minimise the inertial and other losses associated with geared connections.
