Fluorescence Filters
JDSU builds fluorescence filter sets for applications in fluorescence microscopy and other biomedical applications. In one of the more common applications, a filter set is composed of an excitation filter, an emission filter, and a dichroic beamsplitter. A filter set may be designed to work with a single fluorophore or with multiple fluorophores simultaneously.
The superior precision and repeatability of the new Ucp-1 filter deposition platform enables the realization of filters with exceptional blocking levels, high transmission levels, and extremely steep transition zones. The practical result in fluorescence based applications is bright, high-contrast images. The single substrate construction avoids scattering, absorption, and reflection losses that occur with traditional, multi substrate laminated filters, which have adhesives in the optical path. The hard-dielectric coatings are environmentally robust and withstand high optical densities with no noticeable degradation over time.
