    BX51M CONTENTS Correct assembly and adjustments are critical for the microscope to exhibit its full performance. If you are going to assemble the microscope yourself, please read chapter 8, “ASSEMBLY” (pages 27 to 29) carefully. IMPORTANT — Be sure to read this section for safe use of the equipment. —...

  • Page 4: Main Switch

    This microscope employs a UIS2 (UIS) (Universal Infinity System) optical design, and should be used only with UIS2 (UIS) eyepieces, objectives and condensers for the BX2 series. (Some of the modules de- signed for the BX series are also usable. For details, please consult Olympus or the latest catalogue.) SAFETY PRECAUTIONS 1.
  • Page 5 2. Do not use the microscope where it is subjected to direct sunlight, high temperature and humidity, dust or vibrations. (For the operating conditions, refer to chapter 6, “SPECIFICATIONS”.) 3. The BX51M can be used with an intermediate attachment such as a U-CA magnification changer or U-EPA2 eyepoint adjuster.
  • Page 6 Caution If the microscope is used in a manner not specified by this manual, the safety of the user may be imperiled. In addition, the equipment may also be damaged. Always use the equipment as outlined in this instruction manual. The following symbols are used to set off text in this instruction manual.

    USING THE CONTROLS 3-1 Base Voltage Indication (Fig. 3) 1. Turn the brightness adjustment knob @ clockwise to increase the volt- age and make illumination brighter. 2. The numerals on the left of the lamp voltage LEDs ² indicate the ap- proximate voltage.

  • Page 11: Focusing Block

    BX51M 3-2 Focusing Block Adjusting the Focus (Fig. 5) The coarse adjustment knob @ and fine adjustment knob ² are de- signed to raise the stage (i.e. to let the specimen approach the objective) when they are rotated in the direction of the arrows.

  • Page 12: Pre-Focusing Lever

    Pre-focusing Lever (Fig. 8) }The pre-focusing lever ensures that the objective does not come in con- tact with the specimen and simplifies focusing. After focusing on the specimen with the coarse adjustment knob, turn this lever @ in the direction of the arrow and lock; the upper limit of coarse adjustment movement is set at the locked position.

    BX51M Centering the Field Iris Diaphragm (FS) (Fig. 10) 1. Slide the mirror selector lever @ to “BF”. ² 2. Engage the 10X objective by rotating the revolving nosepiece, place the specimen on the stage and adjust approximate focusing. 3. Pull out the FS knob ² on the reflected light illuminator to reduce the aperture iris diaphragm a little.

  • Page 14: Using The Nd Filter Knob

    Using the ND Filter Knob (Fig. 12) }The ND filter is interlocked with the brightfield (BF) light path switching so it can be engaged or disengaged according to the mirror selector lever @. The ND filter makes it possible to reduce the glare when darkfield (DF) ²...

    Adjusting the X/Y-Axis Knob Tension (Fig. 17) ² }This mechanism is provided only with the U-SVRM/SVLM stage. 1. Hold the X-axis knob @ and slide up the Y-axis knob ² up to expose the adjustment knobs. 2. Turning the X-axis adjustment knob ³ or Y-axis adjustment knob | clock- ³...

  • Page 17: Rotating The Stage

    BX51M Rotating the Stage (Fig. 19) # The U-SIC4R2/SIC4L stage cannot be rotated. 1. Slightly loosen the stage clamping screw @ using the Allen screwdriver. 2. The stage can be rotated both clockwise and counterclockwise while holding the stage. # A click may be heard and felt during rotation. However, this is due to the construction of the substage and does not indicate a malfunc- tion.
