Standard 25 ICSB 40-029 e 01/98 2-52.4.2 Compensation of ametropia when eyepiece reticles are usedThe correct use of an eyepiece reticle requires two focusing eyepieces, e.g. Pl 10x/18 Br. foc., to enablecompensation of ametropia. Use the eyelens of the focusing eyepiece to focus on the line figure of the eyepiece reticle; focus onthe edge of the field of view if no eyepiece reticle is used. Focus on the microscope image of a specimen via the focusing drive by looking through the eyepiecewith reticle. When the image and the eypiece reticle are in focus in the above eyepiece, focus the image for thesecond eye via the focusing eyelens of the second eyepiece.The position of the focusing drive on the stand must not be changed.2.5 Setting of interpupillary distanceand viewing height The eyepiece distance is matched to theindividual interpupillary distance by swinging theeyepiece tubes symmetrically towards oneanother. The viewing height can be increased (2-5/A) orreduced (2-5/B) by turning the entire binoculartube through 180°.Fig. 2-5 Setting the interpupillary distanceand viewing height of the binoculartube
