<p>A high-speed, non-mechanical multiple wavelength illumination source is provided, which contains a first light source (32), a second light source (33) providing a different wavelength of light, and a controller (31) for controlling electric current to the first and second light sources. The illumination source is particularly useful in an apparatus for quantitative luminescence ratio photometry and/or luminescence ratio imaging, and in methods of luminescence emission ratio photometry and luminescence emission ratio imaging, and offers particular advantages in photomicroscopy and in microscopic imaging.</p> |
