- Page 19 PL AC IN G THE SP EC IM E N Place the specimen 1 on the stage. Adjust the image by moving the stage control knobs 2 and 3 so that the observed section of the specimen is directly under the objective. The stage attachment features an XY control system.
- Page 20 ADJ U STI N G THE E YE P I ECE T UB ES Use a diopter adjustment on the eyepiece tubes to compensate for the observer's ametropia. The adjustment range is ± 5 diopters. First set the diopter adjustment 1 on both tubes to the middle position. While looking through the eyepiece installed in one tube (with the other eye closed), bring the specimen into focus.
- Page 21 Fig. 17. Adjusting the aperture diaphragm Adjusting the aperture diaphragm. The aperture iris diaphragm is designed to adjust the numerical aperture, not brightness. Setting the aperture iris diaphragm to 70–80% of the numerical aperture of the objective used ensures a good contrast image.
- Page 22 USING OPTIONAL EQUIPMENT U SING THE EYEP I ECE W I TH A SCALE The eyepiece with a scale or grid can be used to make comparative analysis of the linear dimensions of the individual components of an object. The scale is installed in the plane of the field diaphragm of the 10x eyepiece. The eyepiece with a scale is installed in the tube in place of the eyepiece of your microscope.
- Page 23 USI N G THE CA ME RA ( MAGUS B IO 2 4 0T ) The microscope is designed to observe a specimen through the eyepieces and to photograph the specimen. The vertical camera port (trinocular tube) is located on the top of the microscope head. There is a C-mount adapter 1 mounted in the trinocular tube to use the camera.
