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 very steep transition zones. The practical result in fluorescence based applications is bright, high-contrast images.
JDSU’s Ucp-1 platform is a magnetron-sputtering-based deposition system. The high throughput of the system is enabled by a high material deposition rate combined with the incorporation of a load lock which reduces chamber down time. Coatings deposited with the Ucp-1 platform are fully dense and robust, and have the same durability as coatings deposited using other energetic film deposition processes such as ion beam sputtering and ion-assisted deposition.Ucp-1 coatings pass the environmental durability tests cited in ISO-9211-3 Category C, as well as extended cyclic humidity testing as described in MIL-STD-810F (5 cycles) without measurable change in their spectral characteristics.
