OPERATIONAxiolab 5 Default setting of the microscope ZEISS05/2019 430037-7444-001 794 OPERATION4.1 Default setting of the microscope4.1.1 Setting the inter-pupillary distance on the binocular tube• Adjust the individual inter-pupillary distance bysymmetrically swiveling the two eyepiece tubestowards each other (Fig. 4-1).The correct inter-pupillary distance has been setwhen the observer sees only one round imagewhen looking into the eyepieces.4.1.2 Setting the viewing height• Adjust the viewing height to your individualrequirements by swiveling the eyepiece tubesup (Fig. 4-2/A) or down (Fig. 4-2/B).This individual height adjustment in two stages(upper and lower position) is basically possible withall tubes of the Axiolab 5 program. The viewingheight thus achieved depends on the selectedinter-pupillary distance and the tube viewing angle,which may be stationary or variable, depending onthe model. With an inter-pupillary distance of65 mm and a tube viewing angle of 30°, theheight adjustment range is approximately 40 mm.Binocular ergo (photo) tubes (425511-0000-000,425512-0000-000, 425514-0000-000, 425520-9050-000) are provided with continuous verticaladjustment with a range of 44 mm to 50 mm.The binocular part of the ergo photo tube 425520-9050-000 is also continuously horizontally retractableup to 50 mm.The eyepoint angle of the binocular ergo (photo) tubes (425522-9020-000 and 425522-9030-000) iscontinuously adjustable within a range from 8° to 38°.The comfortable binocular ergo tube (425522-9040-000) is continuously height-adjustable by up to50 mm and angle-adjustable from 8° to 33°. This is the ergo tube which received the highest rating andrecommendation from TÜV in terms of microscope workstation ergonomics.Fig. 4-1 Setting the inter-pupillary distanceon the binocular tubeFig. 4-2 Setting the viewing height on thebinocular tube
