High reflectance

High reflectance

The ability of materials to effectively reflect the sun’s energy. Roof materials with high reflectance stay cooler in the sun, reduce energy costs, improve occupant comfort, and reduce the urban heat island effect.

butterfly wings) could induce high reflectance (varying from 65% to 98% with different incident angles) in visible light range [14].
This white marble gives high reflectance and has great significance as good quality.

In manned aircraft images, this is commonly done by laying out large tarps with known low and high reflectance values, thereby allowing each pixel in the image to be corrected according to a linear model.
The foam-like microstructure created during the solvent casting process gives high reflectance without the use of pigments.
It is generally used to measure fiber links and locate fiber breaks, end-to-end loss, high reflectance and optical return loss.
This device achieves cooler sample temperatures through a patented "cool mirror" that has very high reflectance in the UV and near-visible wavelengths, while attenuating reflectance in the longer wavelength visible and IR portions of the solar spectrum.
Expected returns from high reflectance snow-covered sea ice surfaces are approximately 6 photons per laser shot compared to 1 photon per shot from low reflectance open water leads.
UF Grade also has high reflectance performance which will help to increase brightness of LED lighting.
In general, healthy rice plants always have typical vegetation characteristics: low reflectance at visible wavelengths (400-700 nm); high reflectance in the NIR (700-1,200 nm); and low reflectance in wide wavebands in the SWIR (1,200-2,400 nm).
Apart from a considerable cost and limited supply of this material, it has additional problems: high reflectance of this materials reduces contrast ratio, optical properties degrade rapidly below 50 ohms/sq, which limits the size of display produced using ITO without degradation of performance.
As for the TM wave (in Figure 4(b)), reflectance bandwidth is obvious enlarged at incident angle of 88[degrees], however, the high reflectance range of TM wave no obvious increase at incident angels of 30[degrees] and 60[degrees].
