Tunable optical filters lie at the heart of modern spectroscopic instrumentation, enabling selective transmission of narrow spectral bands with dynamically adjustable centre wavelengths. Key ...
Imaging equipment to observe the earth from space provides data for various uses. Wavelength-discriminated imaging at a considerable distance from the earth’s surface is the basic idea behind optical ...
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 ...
