Characterization of High-OD Ultrathin Infrared Neutral Density Filters

October 8, 1998

Author(s)

Simon G. Kaplan, Leonard M. Hanssen, Alan L. Migdall, G Lefever-Button

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, free of

InSb Working Standard Radiometers

October 1, 1998

Author(s)

George P. Eppeldauer, Alan L. Migdall, Leonard M. Hanssen

Standard quality InSb radiometers have been developed and characterized at the national Institute of Standards and Technology (NIST). The InSb radiometers will hold the recently realized spectral response scale of the NIST and will serve as working

Measuring Absolute Infrared Spectral Radiance With Correlated Photons: New Arrangements for Improved Uncertainty and Extended IR Range

January 1, 1998

Author(s)

E Dauler, Alan L. Migdall, N Boeuf, Raju V. Datla, A J. Mueller, A V. Sergienko

New experimental configurations of a system to measure about IR spectral radiance using correlated photons are presented. The method has the remarkable feature that it allows spectral radiance to be measured in the IR in an intrinsically absolute manner

Realization of an Infrared Spectral Radiant Power Response Scale on a Cryogenic Bolometer

January 1, 1998

Author(s)

Alan L. Migdall, George P. Eppeldauer

The National Institute of Standards and Technology [NIST] has developed an IR radiant power response scale for the spectral range from 2 micro υ to 20 micro υ. The scale has been realized on a cryogenic bolometer. The response of this bolometer has been
