Adjusting Channels Of Detection; Adjusting Signal Detection With The Andor Ccd Camera - NT-MDT NTEGRA Spectra Instruction Manual

3. Approach the sample to the lens slowly and very carefully by rotating the manual
approach knob and observing the sample on the display of the viewing system. Control
the lens focus by contrast of the sample image or by focusing the laser beam on the
sample (if the spectrometer laser is on).

NOTE. Remember that in the course of approaching the lens focuses first
on the bottom surface of the glass and only then on the sample.

ATTENTION! If the lens approaches the sample to a distance less its
focal length, it can run into the glass substrate surface thus destroying
itself and/or the glass substrate.
4. For fine focusing, tune elongation of the lens Z-scanner with the slider is shown
on Fig. 9-3.

9.3. Adjusting Channels of Detection

For recording the signal from the sample surface, the following detectors can be employed:
− built-in Renishaw CCD camera;
− Andor CCD camera.
A specific procedure on adjusting channels of exciting and detection depends on the
module used to detect the signal.
