The action of monochromatic ultaviolet light on proteins

Biochimica et Biophysica Acta, 1957
Abstract The ultraviolet inactivation spectra are reported for dry trypsin at 300° K and 90° J, gramicidin, RNA-ase in acid and alkali, and aldolase. Trypsin and RNA-ase, which have relatively large amounts of cystine, have action spectra which differ markedly from their absorption spectra. Their action spectra show a large component which is similar

Degree of paraxiality for monochromatic light beams

Optics Letters, 2008
We introduce the degree of paraxiality as a paraxiality measure of a monochromatic light beam. Computation of this parameter is possible once the plane-wave spectrum of the field being analyzed is given for a starting source plane. On the basis of this definition, quantitative comparisons of the paraxiality of different types of fields are possible. In

BRIGHTNESS SCALES FOR MONOCHROMATIC LIGHT

Scandinavian Journal of Psychology, 1960
By means of amethod of ratio estimation, scale values were obtained for the subjective brightness of various physical intensities of monochromatic light of various wave lengths. In a second experiment the scale was constructed by a method of magnitude estimation.

A monochromatic light system for the analytical ultracentrifuge

Analytical Biochemistry, 1967
Abstract A monochromatic light system employing a xenon-mercury light source and a Schoeffel quartz prism monochromator is described for the absorption system of the Spinco analytical ultracentrifuge. By using conventional photographic techniques, the system may be employed from 235 to 700 mμ. Applications of the system are illustrated and discussed.

Resonant scattering of monochromatic light in gases

IEEE Journal of Quantum Electronics, 1968
The frequency dependence of the differential cross section characterizing the resonant scattering of photons by the atoms of a dilute gas has been investigated. It is supposed that the scatterers are sufficiently dispersed so that interference between different scatterers may be neglected.

Light‐Induced Melatonin Suppression in Humans with Polychromatic and Monochromatic Light

Chronobiology International, 2007
The relative contribution of rods, cones, and melanopsin to non-image-forming (NIF) responses under light conditions differing in irradiance, duration, and spectral composition remains to be determined in humans. NIF responses to a polychromatic light source may be very different to that predicted from the published human action spectra data, which ...

Light Source for Monochromatic Ophthalmoscopy and Fluorescein Angiography

Archives of Ophthalmology, 1979
• A light source for fiberoptic ophthalmoscopes provides seven different spectral illuminations for monochromatic ophthalmoscopy. The unit can also be used for fluorescein angioscopy.
