Photometers or light meters are radiometers that include a filter and photodiode and responds based on the average human eye: the CIE 1924 luminosity function V λ. However, the light sensitive diode ...

How do two colors mix to make a new color? Answer: Think of light as a wave travelling from one place to another, with different colors produced by variation in the distance between peaks of the wave ...

We propose and numerically demonstrate subtractive color filters (SCFs) based on a plasmonic metasurface including coaxial aperture geometry working in the visible range. The Proposed designs involve ...

Highly efficient subtractive tri-color filters of cyan, magenta and yellow with enhanced color purity and robustness have been proposed and realized, by exploiting a silicon-aluminum (Si-Al) ...

Have you noticed that there's always something new to learn? Furthermore, it's only when you are trying to explain something to someone else that you realize where there are holes in your own ...
