117. Absorption Line Evaluation Methods for Wavelength Standards
Published: Date unknown
Authors: C. J. Zhu, Leonard M Hanssen
Abstract: Two methods for absorption line (peak) evaluation based on center of gravity (CG) calculations are described and compared using spectra of the NIST standard reference material (SRM) 1921(a) characterization measurements. These methods are (1) calcul ...

118. Calibration of a Spectral Responsivity Transfer Standard
Published: Date unknown
Authors: George P Eppeldauer, Leonard M Hanssen
Abstract: A NIST-Developed pryoelectric radiometer was characterized and calibrated to extend the NIST high accuracy spectral responsively scale from the visible range to the ultraviolet (UV) and infrared (IR). The transmission of the gold-black coated LiNbO^ ...

119. Characterization of High-OD Ultrathin Infrared Neutral Density Filters
Published: Date unknown
Authors: Simon Grant Kaplan, Leonard M Hanssen, Alan L Migdall, G Lefever-Button
Abstract: We have performed transmittance measurements of metal-film neutral density filters on ultrathin polymer substrates using both Fourier-transform infrared spectrometer and laser-based (3.39 mm and 10.6 mm) systems. The use of ultrathin substrates, fre ...

120. Characterization of Narrow-Band Infrared Interference Filters
Published: Date unknown
Authors: Simon Grant Kaplan, Leonard M Hanssen
Abstract: A Fourier-transform infrared (FT-IR) spectrophotometer system is used to measure the transmittance of infrared band-pass filters as a function of wavelength, temperature, and beam geometry. Measurements are performed using an f/4 beam geometry at no ...
