Wavelength selective reflectors have been widely used in lightemitting diodes, microcavities, waveguides, solar cells and many more. This paper presents the preparation and study of TiO2/SiO2 distributed Bragg reflectors. These multilayer structures were prepared by adopting an easy and cost-effective ...
wavelength bands (520, 808, 980 nm) of light stimulus, which release the actuation system from light scanning position/direction restriction. Three near-infrared dual-wavelength modulated actuators and one visible/infrared tri-wavelength modulated multi-directional walker robot are demonstrated in this...
The infrared band refers to the range of frequencies within the electromagnetic spectrum that occurs above microwaves and below red visible light. It is divided into five parts: near-infrared, short wavelength infrared, medium wavelength infrared, long wavelength infrared, and very long wavelength infr...
This devise is visible and near-infrared light having superior performance in marine as well as the near-infrared wavelength bands in the visible light wavelength band relates to a variable focus lens with a spectrum range surveillance camera, a negative first lens having a concave surface on the...
A lot of detectors created for 940 nanometers incorporate a pre-installed visible-light filter. Filters aren't generally used on the 880-nanometer products mainly because this wavelength is close to the visible spectrum and this kind of a narrow filter might be challenging to manufacture in huge...

Colorant composition consisting essentially of one or more cholesteric liquid-crystalline polymers having a pitch of the helical superstructure of between 760 nm and 500 &mgr;m, and of at least one colorant which absorbs light in the visible wavelength range. Suitable colorants are organic or inor...
For photonics, Stulius and Streifer reported in 1977 [15] the first fabrication of Si33N44 films on a SiO22 buffer on Silicon wafers, for light propagation in the red visible wavelength (632 nm). After some works in the 1980s on the propagation of visible (VIS) light through straight ...
Satellite sensors measuring water vapor operate in different viewing geometries, limb-sounding, occultation and nadir-viewing, and different spectral domains, ultraviolet (UV), visible, near- or short-wavelength infrared (NIR/SWIR), thermal infrared (TIR) and microwave [13]. Accurate quantification ...
Infrared light is a wavelength that is longer than a human hair. This wavelength is the most common color of visible light. Despite its short wavelength, infrared light is also used to see ultraviolet light. This IR material has a high transmitting power. Its benefits are many. There are no...
