A transilluminator is provided for enhanced visualization of an object/specimen during its examination and/or analysis such as during nucleic acid fragment visualization. In the described embodiment, the transilluminator includes a transmittance plate adapted to support the specimen being tested, and an array of LEDs adapted to emit light through the plate for illumination of the specimen. The transmittance plate, LEDs or a combination thereof filters and/or emits light energy within a predefined spectrum of light energy. In one preferred embodiment, the illuminating light is in the ultraviolet or near-ultraviolet light spectrums to stimulate or fluoresce dyes within the specimens. Furthermore, two or more LEDs which vary in wavelength emission may be employed for the purpose of varying the illumination characteristics of the transilluminator.
