  • Device for selecting a light source for measuring the wavelength characteristics of an optical element
    Patent number: 4789237
    Abstract: A device for selecting a light source among a plurality of light sources, for measuring the wavelength characteristics of an optical element comprises: a signal source which generates a modulating signal; a change-over switch connected to the signal source; a plurality of light sources different from each other in wavelength, connected to the outputs of the change-over switch; a coupler coupling the respective outputs of the light sources; a detector for detecting the respective outputs of the light sources; a filter which passes only a component of the output of the detector corresponding to the modulated optical output of a selected light source; and an indicator for indicating the measured wavelength characteristics of a measured optical element. The change-over switch is operated to selectively connect the signal source to a selected light source to modulate the optical output of the selected light source by the modulating signal of the signal source.
