Real Time Digital Filters
Real Time Digital Filters can be used to filter a measured signal in real time. Filter characteristics can be defined by the user to meet the requirements of a specific application. Real-time digital filters are applied in the data conditioning phase. The filters are designed with a graphic design tool and then uploaded to the front-end for real-time calculation. The graphic design tool defines the filter performance vertical axis with a dB scale. The horizontal axis is defined as relative frequency.

Filters
In order to minimize filter roll-off, we start with a quality, highly polished substrate and apply layers of metallization within tight tolerances. Our highly anisotropic ion beam etching process enables us to produce features down to 10 microns. Furthermore, the milling process yields a high consistency from circuit to circuit meaning that whether we produce 1 or 100,000 filters, each one will have consistent filter roll-off characteristics.

Microscope Cameras
In contrast to digital cameras for normal photography, microscope cameras are built to meet the demands of high-end science- and research applications. For maximum light sensitivity they use large CCD or CMOS sensors for image acquisition. Color reproduction is often critical, why features like Microscanning or Color-Co-Site Sampling ensure optimal image quality. Due to the lack of a light absorbing color filter monochrome microscope cameras for fluorescence imaging are even more sensitive.
