Method and apparatus for performing fluorescence correlation spectroscopy, especially multicolor fluorescence correlation spectroscopy

摘要

In the procedure, the light beams are incident parallel to the transparent medium and are deflected toward a focal point inside the transparent medium. This avoids the use of refractive lens systems. The focusing lens system according to the invention enables the bundling of light beams of different wavelength to a point inside the sample.This clearly simplifies the design and adjustment of a multicolor fluorescence correlation spectroscopy device.
