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.
