Cairn's modular photometry components make it (in our opinion) the most versatile fluorescent measurement system available. The open design allows systems to be configured to
the user's individual needs, and to be changed or extended according to future requirements. The systems are suitable for either single, dual or multiple excitation measurements and dual emission measurements (using either single-wavelength or multiple-wavelength excitation).
Systems can be built up from a base of either our filter wheel or monochromator optical wavelength changers, with a range of analogue signal processing modules and digital interfacing options. They can be connected to all popular microscopes, including those made by Nikon, Olympus, Leica and Zeiss, or can be used with the Cairn cuvette holder for cell suspension measurements. A particularly important feature is the ease with which it can be interconnected with other equipment. Not only can our system accept realtime external inputs, but it also provides a full range of continuously available analogue outputs and synchronisation signals. This means that you can get started by adding Cairn components to an existing experimental set-up, whilst retaining the option of extending it to a full Cairn system at any time in the future.
