JDSU’s Color Sensor Filters are based on thin film technology. They are designed and built to match spectral curves such as the CIE or ISO tristimulus functions. JDSU can tailor the spectral response of Color Sensor Filters to meet custom requirements. For example, illuminant and detector correction functions can be combined with a CIE tristimulus function into a single filter.
The superior precision and repeatability of the new Ucp-1 filter deposition platform enables the realization of Color Sensor Filters that have been difficult or impossible to achieve with previous-generation technologies. The relatively small batch size of the platform reduces the barrier of entry for new applications as compared with other filter coating processes. The high deposition rate and loadlocked pumping system enables high throughput in volume production at low cost.
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.
