INSTRUMENT DESCRIPTIONAxio Vert.A1 Operation and Functional Elements of Optional Components Carl Zeiss05/2012 431030-7044-001 372.6.3 CondensersTo allow a quick condenser change, all thecondensers come with a special connection platefor bayonet mounting.The condenser can be rotated in its mount in 90-degree steps (after the bayonet mount has beenloosened and subsequently tightened). (SeeSection 3.1.7.)LD Condensers 0.3 and 0.4 for Sliders− Condenser equipped with an adjustableaperture diaphragm (Fig. 2-17/4) for sliderswith fixed phase stop Ph1/0.3 (Fig. 2-17/1) orPh1/0.4; slider Ph/PlasDIC, H, Ph/PlasDIC(Fig. 2-17/2) or slider Ph/PlasDIC, H, Var(Fig. 2-17/3)− The sliders can be inserted from the right orleft (or from the front or the back).− The center position of the slider is providedwith a neutral density or attenuation filter toguard against glare.− Depending on the type of slider employed,the condenser can be utilized for the brightfield, phase contrast, PlasDIC or VARELmethods.For optical reasons, thePh/PlasDIC, H, Var slider is suitable forcondenser 0.4 only.LD Condenser 0.4 H Ph PlasDIC DIC iHMC− Condenser with an adjustable aperturediaphragm (Fig. 2-18/1) for the bright fieldposition (position 1 of the modulator disk,while the aperture diaphragm is completelyopen for all the other positions of themodulator disk)− Five-position modulator disk (Fig. 2-18/3)and slot for polarizer slider (Fig. 2-18/2)− Depending on the phase stops or slitdiaphragms or the condenser modulesemployed, the condenser can be utilized forthe bright field, phase contrast, DIC, PlasDICor iHMC methods.− Spaces for stickers (Fig. 2-18/4) showing thedesignations of the slit diaphragms, phasestops or condenser modules installedFig. 2-17 LD Condensers 0.3 and 0.4 forSlidersFig. 2-18 LD Condenser 0.4 forH Ph PlasDIC DIC iHMC withInsertable Polarizer Slider DL,Rotatable 90 Degrees
