    Measurement Alignment Adjustment <<See section 3.6 for the operating procedure>> This function allows adjustment of the optical axis of the instrument’s built-in monochromator (spectroscope). The instrument’s optical performance is not guaranteed until the alignment adjustment function has been executed. Failure to perform this adjustment can result in distortion of measured waveforms.
  • Page 23 2.2 Measurement Higher resolution can be obtained since the wavelength resolution is being determined by the spectral line width of the tunable laser source. Also, since the tunable laser source scarcely outputs any other components than the measuring wavelength, and as the noise light which comes out faintly is being totally cut except for the section corresponding to the resolution range of this equipment, an extremely high optical dynamic range can be acquired.
  • Page 24 The power per 1 nm is called the power density. The level axis of the AQ6370B indicates the absolute power per wavelength resolution. For example, if the resolution is set to 0.1 nm, the power per 0.1 nm will be displayed.

    Important Points During Measurement Types of Optical Fibers The instrument can use single mode optical fibers with core diameters of 5 to 9.5 μm, and multimode (GI) optical fibers with core diameters of 50 and 62.5 μm. Functions may be limited or restricted depending on which type of optical fiber is used. The table below shows which of the typical types of fiber may be used and the limitations on their use. Limitations on Wavelength Resolution The maximum wavelength resolution for the instrument is 0.020 nm, which is only obtainable when using a single-mode optical fiber with a core diameter of 9.5 μm or less.

  • Page 220 7.14 Correcting Displayed Values Absolute Level Accuracy The instrument’s absolute level is calibrated with a 9.5 μm single-mode optical fiber. In terms of actual capability, even single-mode optical fibers that do not have a core diameter of 9.5 μm provide nearly the same level of accuracy. Multimode (GI) fiber provides a relatively accurate spectrum if the light source is low- coherent light such as white light, natural light, or an LED. If the light source has high coherency as in the case of a laser beam, interference will occur inside the optical fiber, and the intensity distribution of light radiating from the fiber tip will vary according to the fiber form.
