Cairn Research Limited

Detection

Cairn offers a range of light guide couplings to fit all popular fluorescence microscopes. These components can interface either to the microscope's built-in epicondenser, or, in many instances, directly into the filter cube module. More sophisticated versions offer dual input ports (typically for combining flash photolysis and epifluoresence) and independent field apertures.

Applications

Features

High quality silica lenses for ultraviolet and visible transmission
Standard versions suitable for use with our 1.5, 2, 3 and 5mm light guides
LED versions available for use with our OptoLED light source
Optics optimised for Köhler illumination with high Numerical Aperture objectives
Critical illumination possible on some microscopes
Dual port versions available for combined flash photolysis / fluorescence
Independent field aperture option

Standard Couplings

The table below shows the extensive range that we have avilable "off-the-shelf", and covers the more recent models from Nikon, Olympus, Zeiss and Leica. If you are having trouble finding what you need then please contact our sales department; the numbering system is inevitably quite complicated because there are so many possible itterations. If a coupling is not currently available for your microscope then we will design one for you.
