Cairn Research Ltd. is an independent scientific instruments manufacturer based in Faversham in the UK. We mainly produce instrumentation for fast, sensitive optical measurements, with our equipment being found around the world in laboratories using fluorescent indicators or fluorescent proteins to investigate the dynamics of physiological systems. Our customer base is primarily leading researchers with demanding scientific goals, and many of our products have been developed as a result of our responding to their specific requirements. This has also allowed us to diversify into other areas for which they may have a simultaneous requirement, such as bioluminescence, electrophysiology and flash photolysis, all of which we now support.
