NanoScope Optical Viewing System
Rev. C
213.4 Suggestions
When operating your SPM with the optical viewing system, it is recommended that the tip be
brought close to the sample surface BEFORE aligning the laser with the tip.
If specks of dirt appear on the video image, clean the camera objective’s dust cover (the clear
glass plate located on the business end of the camera). The dust cover is removed by
unscrewing the camera objective. Clean inside and out, then replace.
Use adjustment knobs on the focus mount assembly to raise and lower the camera; however,
tension in the mount assembly’s slide must be maintained sufficiently to prevent the optical
assembly from slipping downward. To adjust tension in the focus mount assembly slide,
counter-rotate left-right adjustment knobs clockwise as shown below:
Figure 213.4a
To increase tension, turn both knobs CW
It is recommended that tension be adjusted with the SPM removed to ensure the objective
does not drop onto the SPM head.
