Adaptation of a High-Accuracy Spectrophotometer for Ultraviolet Work

Autor: K D, Mielenz, R, Mavrodineanu, E D, Cehelnik

Publikováno v: Journal of research of the National Bureau of Standards. Section A, Physics and chemistry. (5)

A high-accuracy spectrophotometer, originally designed for work at visible wavelengths, was modified to permit measurements in the ultraviolet without degradation of its original performance. This was accomplished by equipping the spectrophotometer w

Cross-spectral density propagated through a circular aperture

Autor: E. Tepichín-Rodr Guez, K. D. Mielenz, J. G. Suárez-Romero

Publikováno v: Metrologia. 38:379-384

A method is presented for evaluating the cross-spectral density diffracted by a circular aperture in the Fresnel approximation. Our proposal is a generalization to partially coherent illumination of the classical solution to the problem of near-field

Autor: Charles E. Gibson, Robert D. Saunders, K A Sudarev, V I Sapritsky, S N Mekhontsev, G D Harchenko, K D Mielenz, B. Khlevnoy

Publikováno v: Metrologia. 32:449-453

A comparison of the spectral-radiance scales of the National Institute of Standards and Technology (NIST) and the All-Russian Research Institute for Optophysical Measurements (VNIIOFI) was carried out in 1989 and 1990. The spectral range of the compa

International Intercomparisons of Photometric Base Units

Autor: K. D. Mielenz

Publikováno v: Journal of Research of the National Bureau of Standards

National Bureau of Standards Gaithersburg, MD 20899 In order to evaluate the worldwide consistency of practical implementations of the 1979 redefinition of the candela, the Consultative Committee for Photometry and Radiometry (CCPR) has conducted an
