How to connect the image scanner

Look at the pictures. Scan1.jpg shows the initial looking of your Multiskop.

Remove the T-shaped objective holder and replace it by the new L-shaped holder (Scan2.jpg). In newer versions of the Multiskop this L-shaped holder is already mounted.

In the blue box containing the scanner there is also a yellow ring made of brass. Screw this ring in the L-shaped holder and tighten it with the little key contained in the same box (see Scan2.jpg).

Connect the scanner to the yellow ring and tighten the screw as shown in Scan3.jpg. Never operate the scanner before tightening this screw !

Screw the objective into the scanner (Scan4.jpg).

Connect the scanner to its controller and this controller to the A2 output of the amplifier of the photo detector as shown in Scan5.jpg. The sinusoidal signal, that drives the scanner, is generated by the computer with the aid of the DA-converter and provided at this output. From here it goes to the “MOD” (modulation) labelled input of the piezo controller.

Newer versions of the Multiskop have different detectors. See the red arrow in Scan6.jpg. It is pointing to DAC1 (Digital-to-Analog-Convertor no.1). Here you should connect the piezo controller.

The rotating knob of the scanner controller should be in the most left rotated position and the Off/On switch of the feedback loop should be on, as shown in Scan7.jpg.

The last image (Scan8.jpg) shows how to connect the 12Volt DC power supply to the scanner controller. This is already done if the Multiskop is delivered.

You start scanning by pressing the “Scan” button in the microscopy menu of the Multiskop controlling program. But first select in the listbox the objective you are using. During scanning adjust the focus of the whole image by rotating the knob at the end of the detector arm.
