Example Sentences:
Actinometer
Definition:
(n.) An instrument for measuring the direct heating power of the sun's rays.
(n.) An instrument for measuring the actinic effect of rays of light.
Example Sentences:
(1) The quantum yield of the primary photoprocess in light-adapted bacteriorhodopsin (phi 1) was determined at room temperature with low-intensity 530 nm neodymium laser excitation, with bovine rhodopsin as a relative actinometer.
(2) The irradiation dose was determined by a modified potassium ferrioxalate actinometer according to Calvert and Pitts.
(3) The radiation in the visible and ultraviolet regions from submerged, transient electrical arcs was measured with a K(3)Fe(C(2)O(4))(3) chemical actinometer and was compared to the bactericidal effect obtained with the same electrical arrangements.
