Two-way image splitter 

The industry leading Optosplit II image splitter from Cairn Research divides an image into two separate, spatially identical components. Displayed side by side on a single chip, this elegant device effectively doubles your research capacity with one camera. 


 Splitting is usually performed on the basis of wavelength, allowing applications such as ratiometric calcium imaging or FRET, however, polarising beamsplitters are also supported. The two images can be captured simultaneously offering a major benefit over manual or electronic filter changers. A rectangular aperture is used to define the region to be imaged, with a set of simple controls allowing the user to align the two channels on a variety of camera chip sizes. The Cairn Optosplit II can significantly widen the scope of any fluorescence imaging system.
