tunable filters News
Filtering Visible Light According to Wavelength and Bandwidth
Mar 30, 2020 — Broadband light sources such as supercontinuum lasers and lamps have been in high demand in the photonics industry due to their versatility and optimal output power. Some supercontinuum lasers have an output power in the range of tens of watts with a wavelength range that covers the entire UV-VIS range and a portion of the NIR region. With these performance specifications, the combination of a tunable filter and a broadband light source is more efficient than multiple discrete light sources....
Color-Changing Mechanism Behind Cephalopods Revealed
SANTA BARBARA, Calif., July 29, 2013 — The mechanism responsible for the dramatic color changes in underwater creatures such as squid and octopuses has been revealed. Understanding how cephalopods change color could lead to new approaches to making tunable filters and switchable photonic...
Coupled Waveguide Technology Enables Multiple Imaging Advances
Apr 1, 2013 — This approach enables not only wide-range tunable filters, but also an image demultiplexer that forms the core of a multispectral imaging system that captures high-resolution images in real time over a broad wavelength range. Waveguide technology is...
Microscale Actuators Drive Macroscale Optical Element
Aug 1, 2004 — A team of engineers has reported the development of a rigid-body motion generator based on a two-dimensional array of deformable micromembrane actuators. The generator has a variety of potential optical applications, including use with tunable...
Companies Form Manufacturing and Distribution Alliance
Nov 1, 2003 — NP Photonics of Tucson, Ariz., and Chromux Technologies Inc. of Oxnard, Calif., have formed a partnership in which Chromux will be the exclusive manufacturer of NP Photonics' compliant MEMS products and their distributor in China and South Korea....
