Several light sources produce light across various wavelengths. While this wavelength spectrum can be useful in lighting applications, other applications require light with a restricted visible ...

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).

What is electromagnetic interference and what causes it? The main approaches to filtering out EMI and reducing its impact. How to evaluate EMI filters and what to know about designing them.
