Abstract:
1. A double-light cabinet for testing a biological sample labeled with fluorochrome, comprising: a case having a chamber; a light unit, which is provided in the chamber of the case, having first light sources to emit a first light with a first wavelength and second light sources to emit a second light with a second wavelength, wherein the first light excites the fluorochrome, and the second light illuminates the biological sample; a diffusion unit received in the chamber of the case, wherein the first light and the second light emit to the diffusion unit to form a first surface light and a second surface light and emit to the biological sample to excite the fluorochrome to generate a third light with a third wavelength; and a filter unit comprising a plurality of first areas and second areas, wherein the first light sources and the second light sources are under the diffusion unit in an arrangement of the first light sources respectively facing the first areas and the second light sources respectively facing the second areas; wherein the diffusion unit is a ground glass plate or an acrylic plate; wherein the first areas of the filter unit are coated with dye that the first light emits to the diffusion unit through the first areas, and the second areas are transparent so that the second light emits to the diffusion unit through the second areas.
