About This Webinar
Optical filters are key photonics components providing wavelength selectivity in many applications, transmitting specific wavelength bands to the desired destination of a detector or receiver and reflecting other wavelength bands to different destinations or blocking the undesired bands entirely.
For certain applications including telecom PON, fluorescence spectroscopy, and 3D cinema, it is necessary to select multiple signal bands at different wavelengths on the same optical path. In such cases optical filters with multiband spectral performance are required.
In other applications including order sorting in machine vision or multi-spectral imaging in earth observation, it is advantageous to provide spatially varying spectral performance enabling different regions on the imager or detector to observe different individual spectra. These cases are enabled by multizone optical filter arrays.
Palidwar describes the needs for both multiband and multizone varying optical filters, and some of the challenges and solutions with the design and manufacture of these multifunctional optical filters.
