These coatings are compatible with a proprietary dichroic filter technology enabled by the Microdyn sputtering process, which is said to yield high performance, uniform, transparent conductive filters that remain stable while withstanding high thermal loads and changes in humidity.
Fluorescence emission was evaluated with a Zeiss Photomicroskop III equipped with a Photometer 03 microfluorimeter, HBO 100-W mercury vapor light source, dichroic filter (FT 580), exciter filter (PB 546/12), and barrier filter (LP 590).
The consequences of the dichroic filter, mismatch of emission spectra reflected in s([lambda]), and disparity of the extinction coefficients are examined.
A useful and distinguishing feature is oocyst autofluorescence, which appears blue by Epi-illumination and a 365-nm dichroic exciter filter and green by a 450-nm to 490-nm dichroic filter.
The function of the camera must be split between processing the incoming light and focusing on the dichroic filter.
The performance of a dichroic filter is determined not only by the quality of its coating, but also by the substrate material itself.
After optimizing spectral bands, application-specific cameras can be scaled to production using a proprietary technology to micropattern a passive dichroic filter array onto camera sensors.
has begun commercial shipments of optical network and digital imaging products based on its Dichroic Filter Array (DFA) technology.
The high degree of manufacturing reproducibility allows mass production of the dichroic filter coatings within very narrow tolerances.
This effect is achieved by the insertion, inside the panels, of dichroic filters that make the surfaces shimmer seductively with delicate chromatic variations that, as in the glitter series, are explicated in the titles (CL9GN35 Sunset Bright Green, 2016; CL2 Blue Shadow, 2015-16; and CL9 Pink Shadow, 2015-16).
