Abstract
The directional–hemispherical reflectance measurement facility at the National Physical Laboratory (NPL) has recently been upgraded. Improvements to the facility include replacement of the grating spectrophotometer with a Fourier transform spectrometer (FTS), minimization and correcting for the effects of heating of the test sample, better alignment (using visible radiation), the use of an intermediate field stop, and correcting for instrumental and relay optics drift by using a blackbody. Measurements obtained with the new facility are presented and discussed.
