Interference filters are frequently employed in transmissive configurations where the light passes through the filter to produce a specific effect (band-pass, long-pass, short-pass, among others).

Widespread availability of Wi-Fi functionality on smart devices, the potential for an overall improved quality of service (QoS), and the ability to stream video to smartphones in dense environments ...

Optical Filters are used to selectively transmit or reject a wavelength or range of wavelengths. Optical Filters are used in applications such as fluorescence microscopy, spectroscopy, clinical ...

Researchers at Seoul National University have developed the first hardware-based acoustic band-pass filter that can isolate machine fault sounds in environments with noise levels up to 100 dB. Using ...
