Abstract
The development and evaluation of an optical system for a new spectral directional emittance facility at NIST is reported. The imaging quality and signal contributions due to out-of-field-of-view scattering, commonly characterizedby the size-of-source effect (SSE) parameter, have been measured across the spectral range of 0.65 m to 4 m by three independent methods. The SSE measurement results of scatter levels not exceeding 2-3 parts in 104 are consistent and exceed the design targets. The potential application of the optical system to construction of a portable instrument with low scatter/emission and an operating spectral range of 0.65 m to 20 m are discussed.Proceedings Title
