ABSTRACT:
A wavelength sub-dispersive device receives light from a standard light source producing light having a narrow bandwidth and having an intensity greater than that of light to be detected. The sub-dispersive device is provided for identifying the wavelength of the dispersed light by a main dispersive device, which is detected by a main detector. Light from the standard light source does not irradiate the main detector. If the main detector is irradiated with the light from the standard light source, the detection of the main detector is disturbed by its high intensity.
