At this point, the film was ready for reflectance evaluation and cross-sectional microscopy.
1) in the reflectance spectra of both the surface samples in the visible (590 to 630) nm and near-infrared (750 to 780) nm bands.
Reflectance is targeting a large opportunity and has partnered for the manufacturing and distribution skills required to tap the market.
The Display Reflectance Spectrophotometer combines Gamma Scientific's high-speed RadOMA spectroradiometers with optically stable and durable fixed angle gonioreflectometer heads to test at production speeds.
This is because the SOC 400T has the capability to measure reflectance over a large spectral range and subsequently evaluates emittance over a large temperature range.
The coating shows more than 90% diffuse reflectance, and is also light stable.
As the reflectance r is increased, more and more of the total illuminance ET is due to light interreflected from the room surfaces.
The reflectance was measured from 400 nm to 700 nm with the interval of 10 nm.
Measured spectral transmission and reflectance histogram of investigated prints on polypropylene foil printed with UV inks and solvent based inks have been shown in Fig.
The interior surface of each tube was painted black in order to absorb radiation scattered in reflection during a transmittance measurement or scattered in transmission during a reflectance measurement.
Feathers from each bird were taped to dark black paper with less than 10% reflectance (CANSON #425 Stygian black) overlapping in a way that mimicked how they would lay on the bird.
The use of elements which have a very high Solar Reflectance Index has been stressed throughout the design process.
