Multiwavelength transilluminator for absorbance and fluorescence detection using light emitting diodes

摘要: Systems, devices and methods are provided for viewing a pattern of biological material stained with dyes capable absorbing, scattering or fluorescing light when illuminated by emitting diodes (LEDs). The system includes source containing multiple arrays different LED types at wavelengths optimized detecting specific dyes, diffuser, detector viewer, optional optical filters to ensure that the only reaching viewer is produced fluorescence various within wavelength band. absorbance scatter. can be selected in any combination during illumination their intensity adjustable over range from 0-100%. A method also comparing patterns two more contained single material.
