Fluorescence filters

EURECA offers a range of very high quality fluorescence filters for the separation of fluorescent light from the excitation light. Short-wave light, which excites fluorochromes to fluorescence is reflected, while the long-wave excitation light passes through.

Available are filters in various standard sizes. The indicated sizes are the mechanical sizes, the area of the clear aperture is about some millimeter less. Other customized sizes are possible on request.

In addition to the classical fluorescence microscopy, in which these filters are mainly used, there are some more advanced microscopic applications such as confocal laser scanning microscopy and the multi-photon fluorescence microscopy. Also some other methods, in which the resolution is improved by passing the Abbe limit, are included.
