(a) The spectrometers cannot be amplitude corrected below 380 nm.

(b) A large difference in the relative response of the chip from the UV to the visible inhibits reliable power readings in the UV when performing broadband measurements. Features in the UV may still be visible with the use of a bandpass or shortpass filter to prevent saturation at longer wavelengths.

(c) There is a Ø1.2 mm mechanical aperture adjacent to the entrance slit which limits the effective dimensions of the slit to 20 µm x 1.2 mm. See Slit Dimensions Note, below, for more details.

(d) Ratio of saturation voltage to dark current voltage.

(e) Scan rates up to 200 Hz (with 5 ms integration time) are only possible when using internal triggering. In external triggering mode, the maximum scan rate for the same integration time is 100 Hz.

(f) With 10x averaging, depending on integration time; for single-shot applications, signal-to-noise is limited by the dynamic range of the CCD.

(g) If the fiber patch cable is switched or replaced, the spectrometer will need to be recalibrated.

(h) The M16L01 is an SMA to FC/PC fiber patch cable that uses the same fiber (FG050LGA) as the M14L01 patch cable included with CCS100 and CCS175 spectrometers. Each spectrometer is calibrated with the included patch cable.

(i) The M91L01 is an SMA to FC/PC fiber patch cable with a wavelength range of 250 to 1200 nm that can be used with the CCS200 spectrometer. Each spectrometer is calibrated with the included patch cable.

Note: These specs are valid only in combination with the included fiber patch cables.
