  • Page 5: Safety Precautions

    CX23 Safety precautions If the product is used in a manner not specified by this manual, the safety of the user may be imperiled. In addition, the product may also be damaged. Always use the product according to this instruction manual.
  • Page 6 CAUTION - LED (light emitting diode) Do not look directly at the light from LED for a long time. If you feel that the light from LED is too bright during observation, adjust the light intensity using the brightness adjustment knob and continue observation. The LED built in this product is basically eye-safe. However, do not look directly at the light from LED for a long time while feeling too bright, since it may cause damage to your eyes.
  • Page 7 CX23 Handling precautions · This product is a precision instrument. Handle it with care NOTE and avoid subjecting it to a sudden or severe impact. · Never disassemble any part of the product. Otherwise, failure could be caused. · The objectives are screwed in tightly to prevent them from being loosened during transportation.
  • Page 8 Maintenance and storage Do not leave stains or fingerprints on the lenses and filters. If they get dirty, blow away dust with a commercially available blower and gently wipe the lens or filter with a piece of cleaning paper (or clean gauze). Only when cleaning fingerprints and oil stains, slightly moisten a piece of cleaning paper with commercially available absolute alcohol and wipe them off with it.

    CX23 Observation procedures Turning ON the LED illumination Set the main switch a to (ON). Rotating the brightness adjustment knob b in the arrow direction increases the brightness and rotating it in the opposite direction decreases the brightness. The values shown around the knob represent the rough indication of brightness.

  • Page 14: Placing The Specimen Slide

    Placing the specimen slide Rotate the coarse focusing knob a in the arrow direction to fully lower the stage. Press the holding lever knob b backward (arrow direction) to open the specimen holding lever c , and place the specimen slide d by sliding it on the stage from front toward back.
  • Page 15 CX23 Stage operation in X/Y direction Scale of specimen position By reading and taking a note of X-axis and Y-axis scales (coordinates) of the specimen observation position on the specimen slide, you can return to the original observation position easily even if the specimen is moved.

  • Page 16: Selecting The Objective

    Selecting the objective Hold the revolving nosepiece a and rotate it so that the intended objective comes exactly above the specimen slide. · Do not rotate the revolving nosepiece by holding the NOTE objective. · Be careful if you rotate the revolving nosepiece while observing the edge of the specimen slide with the high magnification objective (40X, etc.), the objective may interfere with the specimen holder.

  • Page 17: Adjusting The Interpupillary Distance

    CX23 Using the pre-focusing lever The pre-focusing lever prevents the specimen slide from being damaged by collision between the specimen slide and objective. After bringing the specimen into focus with the objective which has the shortest WD, rotate the pre-focusing lever a clockwise until it stops.

  • Page 18: Adjusting The Diopter

    Adjusting the diopter. The diopter adjustment is to compensate for the difference in eyesights of left and right eyes of the observer. Rotate the diopter adjustment rings a of the right and left eyepieces and move each scale “0” to each index b . Engage the 10X objective in the light path and rotate the coarse/fine focusing knobs to bring the specimen into focus.

  • Page 19: Adjusting The Condenser Position

    CX23 Using the eye shades When wearing eyeglasses Use the eye shades in the normal, folded-down position. When not wearing eyeglasses Extend the folded eye shades in the arrow direction. Since the eye shades prevent the unnecessary light from entering between eyepieces and eyes, you can observe the specimen comfortably.

  • Page 20: Adjusting The Field Diaphragm (Fs)

    Adjusting the field diaphragm (FS) The field diaphragm is a diaphragm to adjust the illumination area of the specimen. By adjusting the illumination area slightly wider than the field of view depending on objectives to be used, the excess light can be blocked to acquire the image with good contrast.
  • Page 21 CX23 Rotate the field diaphragm ring f in the direction shown in the picture on the left to narrow down the field diaphragm. (Picture A shown below) Field diaphragm image Eyepiece Field of view The field diaphragm image in view is slightly blurred.

  • Page 22: Attaching The Darkfield Ring Slit (For Darkfield Observation Only)

    Attaching the darkfield ring slit (for darkfield observation only) For darkfield observation, the darkfield ring slit CH2-DS (option) must be attached to the condenser. Remove the auxiliary lens unit a attached to the condenser. When removing the auxiliary lens unit a , be sure to hold NOTE it and push it down.

  • Page 23: Observation

    CX23 Observation Engage the objective to be used in the light path and bring the specimen into focus. (See page 12.) Rotate the brightness adjustment knob a to adjust the brightness of the LED illumination. (See page 9.) Acquiring the image with the camera The observed image can be acquired by attaching the camera adapter and the digital camera for microscope to the trinocular tube.

  • Page 24: Using The 100X Oil Immersion Objective

    Using the 100X oil immersion objective · Apply the immersion oil specified by Olympus to the tip of the 100X oil immersion objective. NOTE Otherwise, the observed image is not in focus. · Always use the immersion oil provided by Olympus. Using the immersion oil which is not provided by Olympus cannot deliver the intended optical performance.

  • Page 25: Glossary Of Optical Performance Terminology

    CX23 Glossary of optical performance terminology Total magnification The size of the specimen image to be observed is obtained by multiplying the eyepiece magnification by the objective magnification. This value is referred to as the total magnification. Example: Eyepiece (10X) x Objective (40X) = 400X Resolution The resolution is the ability of the lens to separate the image created by multiple proximal points.
  • Page 26 Aperture diaphragm The aperture diaphragm is a diaphragm to adjust the numerical aperture of the condenser. Adjusting the numerical aperture of the condenser appropriately with respect to the numerical aperture of each objective allows you to observe the specimen with the best contrast and resolution. In general, since the contrast of the specimen to be 70-80% observed with microscope is low, it is appropriate to adjust...
