OptoSpin with Camera

OptoSpin is now fully integrated into NIS-Elements (Nikon advanced microscope software)

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. Our previous design of this type used a relatively small wheel with 12.5mm diameter filters in order to further reduce the inertia – and hence the response time – but by using a newer and much more powerful type of motor, we have been able to obtain similar performance with this 25mm filter design.

2x OptoSpin25's mounted together to produce a 10 position filter wheel, mounted on a single microscope port before entering the camera. More examples of system integration can be found here.
