Abstract: An apparatus for producing an image of blotting membranes includes an enclosure, light source, optical system, photodetector, and beamsplitter. The enclosure supports a blotting substrate comprising a first probe characterized by an excitation wavelength and an emission wavelength and a second probe characterized by an excitation wavelength and an emission wavelength. The light source directs diverging light to illuminate an entirety of the active area. The optical system forms an image of the entire active area and comprises an optical filter, the optical filter having an optical characteristic highly transmissive of light at the emission wavelengths and highly reflective of light at the excitation wavelengths. The beamsplitter may comprise an optical characteristic that is highly transmissive of light at the first and second emission wavelengths and that is highly reflective of light at the first and second excitation wavelengths.
