On the light source side, we are showing our new MultiLED four channel system, which allows you to use our standard LED heads to choose whichever wavelengths you require, and its many new facilities include some powerful programmable timer facilities that can control other equipment in addition to the LEDs themselves. But clearly the star of the show has been our new Optospin50 filter wheel, which is one of Martin’s creations, and the fact that Martin is also writing this piece of propaganda is of course entirely coincidental. Actually it accepts components based on the slightly larger SM2 two-inch thread standard, but somehow “OptospinSM2” doesn’t have quite the same ring to it. But seriously, it has attracted a fair amount of curiosity, as people have been asking why we have made anything that big. In answer to this we explain that it’s not only because we can, but that it can also potentially take lenses, including lens assemblies, and perhaps even filter cubes, as well as rather large filters. So they tend to go away looking rather thoughtful, in which case we may well end up selling some alongside our established 25mm and 32mm designs!
