basic adjustment the Kontrasttubus
equipment of the guns with modulators:
•
They receive two illustration-lateral modulator guns (fig. 5/43) with the Kontrasttubus. In order to save adjusting expenditure, one is
equipped this gun also firmly inserted phase contrast modulators of 100 pos KT and 100 neg KT for the objective REAR ONE 100x.
All remaining eyes of the guns can after free choice and in free one on the other follow with modulators KT for positive and negative
phase contrast, differential interference contrast and central dark field to be occupied.
The shape of the modulator versions and the appropriate photographs in the gun exclude the wrong inserting of the Modu latoren.
The modulator 12.5/25 DIK KT functions both with the objective 12,5x and with the objective 25x.
If an eye of the picture-lateral modulator gun is not to be equipped with a contrast modulator (light field), indieses eye the
modulator “0” to begin.

which modulator is in the path of rays.

sequence of the modulators cond must be the same as the order of the modulators KT!
White writing panels in the window of the gun mark that is to be read off, which modulator in the path of rays is.
