GRYFN offers a custom spectral reflectance panel deployment kit for easy in-field deployment of spectral reflectance panels. Reflectance panels are utilized in Hyperspectral data collection as a calibration method for converting radiance data captured by a hyperspectral sensor to analysis-ready reflectance data.
GRYFN's standard Spectral Reflectance Panel Kit comes as a set of two convenient carrying cases of 1.2m x 0.6m x 0.035m dimensions. These cases also make the target panels easy to transport and setup in the field, with no stakes or extra weights required. Inside each case, weighing in just under 7kg, are two, side-by-side, 1.10m x 0.54m, rigid di-bond panels coated with an actinically stable and waterproof fluoropolymer paint. Each panel is painted with a different reflectance percentage paint, of 11%, 30%, 56%, and 82% reflectance, respectively.

Rigid Aluminum Di-Bond airborne sensor reference panels are painted using a custom formulated coating pigmented to achieve diffuse hemispherical reflectivity (DHR) levels of 11%, 30%, 56% and 82% (maximum white).
The reflective coating consists of a pigmented Type UF200 fluorourethane polymer that tolerates environmental exposure for an extended period of time without significant changes in spectral reflectivity. The coating is pigmented to present a matte reflecting surface with a band average DHR across the visible, Near-IR and SW IR domains (420nm to 2500nm).
Spectral diffuse hemispherical reflectivity (DHR) data are acquired from each of the painted Aluminum Di-Bond panels. These reflectance data are collected using a Perkin-Elmer Lambda 1050 Spectrophotometer with a 150mm diameter integrating sphere covering the spectral domain of 350nm to 2400nm relative to a Spectralon (trademark of Labsphere, Inc.).
Extended spectral reflectivity data are gathered from 2000nm to 3000nm using a Nicolet iS50 FTIR spectrophotometer with a Pike integrating sphere. These extended wavelength FTIR data are acquired relative to a gold coated reflectance standard. DHR files are provided.
