The Optosplit III triple image splitter from Cairn Research is a simple device for deviding an image into either one, two or three separate, spatially equivalent components which can be displayed side by side on a single camera chip. Splitting is usually performed on the basis of wavelength or polarisation, allowing applications where there is a requirement for simultaneous, or high speed, acquisition of multiple emission bands or polarisations states. The simultaneous acquisition of up to three images offers a major benefit over manual or electronic filter changers, as there is no longer a need to pause acquisition while the filter position is changed. This allows your camera to be operated at the very fastest capture rates it is capable of achieving
