Trapped (cold) ions are a research topic with increasing interest over the last few years because of their possibility to store Qubits (quantum bits) and the related use for quantum computers. Of course, it is not only important to use them, but to know their behaviour in detail via various basic experiments.
Sill Optics has designed lenses both, for just observation and observation combined with laser focusing for these experiments. Those lenses are exceptional for their high NA and adjustment to specifi c wavelengths (UV to IR). As the vacuum cryostats diff er in dimension (e.g. the window thickness) every lens has to be designed specifi cally for the existing conditions.
Adaption for your window thickness is possible. We are also pleased to develop lenses according to your requirements.
