Abstract
A multi-purpose optical scanner that is provided for performing different type of high sensitivity imaging of planar biochemical samples. These types of samples include stimulable phosphor image plates, fluorescently labelled samples like electrophoretic gels, TLC-plates, blots etc. or multi-well support of samples and colored planar samples. According to an embodiment of the present invention the multi-purpose optical scanner comprises a measurement unit, a sample support and a scanning mechanics to provide relative movements between the sample on the sample support and the measurement unit. The measurement unit includes a fiber-coupled light source and a measuring head having a fixed light source, a detector, optics and a holder for interchangeable and application specifics filter cubes. The filter cubes include necessary filters and beamsplitters for different operating modes and applications. The orientation of the beamsplitter in the specific filter cube determines which light source will be in use.
