Notch filters are commonly called suppression filters, band-stop filters, etc. The characteristic of this filter is that it can pass most wavelengths with almost no loss, and the specified band (stop ...

An array of electro-optical components fabricated as a silicon-based photonic IC provides narrowband passband and notch filtering above 10 GHz. How an electro-optic PIC can implement RF filtering ...

A Raman Filter is a precise optical filter used in Raman spectroscopy. When placed in the beam path, these filters transmit Raman scattered light to the spectrometer while selectively blocking the ...

Benchtop Raman spectroscopy instruments and—more recently—handheld Raman spectroscopy instruments, which are more frequently used for forensic screening, historical research, and pharmaceutical ...

The Internet of Things (IoT) is common everywhere, from households to industrial environments, allowing “smart” device behavior. As a result of an environmental factor or from information offered by ...
