Page 3: Unpacking, Assembly, Preparation For Use
UNPACKING, ASSEMBLY, PREPARATION FOR USE UNPACKING All MEIJI TECHNO microscopes are usually supplied in an expanded polystyrene, 2-part case and this should be used for storage, possible transport in the future, etc. If your order includes a wooden storage cabinet, release the fixing screws holding the limb and base from the cabinet and withdraw. -
Page 4: Operating Instructions
When in place insert eyepieces in the eyetubes of the binocular body and mount the objectives on the centering objective nosepiece, starting with the lowest magnification, but positioning the 10X in the fixed (not centerable) opening. Then position the others to the right in order of increasing magnification. A focusable cross-line eyepiece should be used in the slotted eyetube. - Page 5 After you have focused on the specimen proceed as follows:- (1)Move the sliders on which the two binocular eyepiece tubes are mounted in and out until the distance between them is exactly the same as the distance between the pupils of the observers eyes. (This is the interpupillary distance .) (2)When this is done, note the dimension which is Window...
- Page 6 SAFETY AUTO-STOP FOR OBJECTIVES AND STAGE PLATE In order to protect specimen slides and objective lenses from accidental damage, the 20X or bigger power lenses are designed to retract at the tip by built-in spring. Besides, Auto-Stopper is equipped in the microscope limb for further safety.
- Page 7 The Analyzer is mounted in an in-tube slider which moves the analyzer in and out of the optical path. When “in”, and with the substage polarizer also “in” and set at 0 degrees, these elements are said to be “crossed” and the field of view is said to be “extinguished”. In this condition the field of view is dark - except for optically active elements in the field, which rotate the angle of polarization and thus become visible against a dark background.
- Page 8 The Polarizer should be inserted into either of the Filter Receptacles on the Reflected Light Illuminator. Analyzer Slide in the Analayer into the optical path. Adjusting knob @1 The above two processes bring on a state of Polarizer CROSSING between Polarizer and Analyser, making the field of view quite dark.

Note: It is important that you change magnifications by rotating the milled nosepiece ring, not by grasping and pulling the objective barrels. Doing this puts strain on the objective housings which can cause some decentering. BERTRAND LENS The ML9400 series polarizing microscope features an in-tube, slide-in Bertrand Lens. Fitted with it is a field-limiting aperture which allows isolation of small features in the center of the field. -
Page 10: Camera Operation
CAMERA OPERATION (1)Fix your 35mm SLR camera, T2 Adapter and a photo (camera) eyepiece on the MA150/50 or MA150/60 Camera Attachment, then mounting this assembly on the straight tube of the trinocular body. (2)Pull out the lever on your trinocular body so as to send the image both to the camera and the visual eyepieces. - Page 11 REFLECTED LIGHT ILLUMINATOR (1) Loosen the Clamp screw and turn the Backing plate clockwise to the slot. Then pull out the Backing plate from the light source housing. Clamp screw (2) After making certain the old bulb is cool to the Backing plate touch, remove it by pulling straight out of its socket.
