摘要：

Pressed polytetrafluoroethylene (PTFE) powder is commonly used as a reflectance standard for bidirectional and hemispherical geometries. The wavelength dependence of the reflectance factor of PTFE is presented for the near-infrared spectral region (800 nm to 1600 nm) for the 45 degrees/0 degrees geometry, as well as in the visible spectral region (380 Nm to 800 nm) for comparison with previously published results.
