"A proposal and realization of a testing equiment composed of an iodine stabilized laser etalon with a wavelength of 633 nm and furthermore of and electronic system for measurement of beat frequencies together with computer processing of measured data. The laser etalon must fulfil the accuracy of the wavelength in limits given by CIMPM of 1992. Lambda i = 632,991 398 22 nm with a relative standard uncertinty of 2.5.10 on -11 and an electronic system automatically processes results of measurement by a computer and prints a certificate. The equipment is determined for testing the vacuum wavelength of laser interferometers."@en . . "3"^^ . . "Laser wavelength etalon for testing laser interferometers"@en . . "1"^^ . . . . .
