3. The outer surface of the optics should be inspected and cleaned periodically using an air bulb. If dirt remains on the optical surface, use a soft, lint free cloth or cotton swab dampened with a lens cleaning solution (available at camera stores). All optical lenses should be swabbed using a circular motion. A small amount of absorbent cotton wound on the end of a tapered stick makes a useful tool for cleaning recessed optical surfaces. Avoid using an excessive amount of solvents as this may cause problems with optical coatings or cemented optics or the flowing solvent may pick up grease making cleaning more difficult.
4. Store the instrument in a cool, dry environment. Cover the microscope with the dust cover when not in use.
5. ACCU-SCOPE microscopes are precision instruments which require periodic servicing to maintain proper performance and to compensate for normal wear. A regular schedule of preventative maintenance by qualified service personnel is highly recommended. Your authorized ACCU-SCOPE distributor can arrange for this service

COMPONENTS DIAGRAM

ASSEMBLY DIAGRAM

• The diagram below shows how to assemble the various components. The numbers indicate the order of assembly.
• When assembling the Microscope, make sure that all parts are free of dust and dirt, and avoid scratching any parts or touching glass surfaces.

DETAILED ASSEMBLY

• Mounting the Stereo Head (Fig. 1)
  Loosen the lock screw 1 on the stand and insert the stereo head 2 into the bracket of the stand. Tighten the lock screw 1 to secure the stereo head.

• Installing the Eyepieces (Fig. 1)
  Remove the eyepiece dust caps 3 and insert the eyepieces 4 until they stop as shown in Fig. 1.

• Installing the Stoneholder (Fig. 2)
  The stage has two stoneholder mounts 6 on either side of the stage where you can attach the  stoneholder 5

Installing the Fluorescent

• Overhead Light (Fig. 3)
  • Connect the overhead fluorescent light to the front of the stage by lining up the male and female holes on the snap connector 2 .
  • Once connected, slide the securing threaded connector into place. Hand-tighten the connector 1 .
  • If possible, it is recommended to further tighten the connector by using rubber tipped pliers. This will ensure that the gooseneck will not loosen and rotate as the overhead fluorescent light is being used.
• Installing the Optional LED Light (Fig. 3A)
  • Remove the plastic cap covering the opening to the LED socket. Insert the LED light guide into the socket and seat it as deeply as possible.
  • The LED light may be varied in intensity by adjusting the intensity dial labeled “Reflected” on the side of the Gemstand.

ADJUSTMENT & OPERATION

• Rotating the Base (Fig. 4)
  Rotate the Microscope to a suitable position for viewing comfort by gently pushing the base 1 .

• Adjusting the Tilt of the Stand (Fig. 4)
  The tilt of the stand is adjustable by holding down the front of the base 1 with one hand, and taking hold of the bracket with the other hand and then pushing or pulling the bracket to obtain the most comfortable viewing position. The stand can be adjusted from 0-38º.

• Adjusting the Rotation Tension Of the Focus Adjustment Knob (Fig. 5)

  • To adjust tension, hold both left and right focus adjustment knobs 2 with both hands, hold the left knob (to prevent it from turning), and rotate the right knob clockwise to increase (tighten) or counterclockwise to decrease (loosen) the focus knob tension.
  • After tension adjustment has been completed, always rotate both adjustment knobs in the same direction.

• Adjusting Interpupillary Distance (Fig. 6)
  

  • Different users have different interpupillary distances (this distance is between the centers of the pupils of each eye). When the operator changes, it will be necessary to adjust the interpupillary distance.
  • While looking through the eyepieces, hold the left 1 and right 1 eyetubes of the viewing head and adjust the eyetubes by opening or closing them until the left and right fields of view coincide completely and you are able to see a complete circle.

• Adjusting the Diopter Ring (Fig. 7)

  • Close the baffle by turning the baffle control knob 2 clockwise, and close the iris diaphragm by turning the iris diaphragm control lever 3 clockwise.
  • Set the diopter rings 4 of both eyepieces to the “0” position (do this when users change, because different users have differing diopters).
  • Rotate the magnification selector knob 5 to 3x, and rotate the focusing knob 6 to focus on the iris diaphragm.
  • Rotate the magnification selector knob to the 1x magnification position 5 and adjust the diopter ring 4 on left eyepiece to focus the specimen – repeat for the right eyepiece.

• Adjusting the Bottom Illumination (Fig. 8)

  • Plug the GEM base into a 110v power supply outlet.
  • Turn the main switch 1 to the “I” (on) position, and rotate the brightness adjustment knob 2 to obtain a comfortable brightness.

• Adjusting the Iris Diaphragm (Fig. 9)

  • The iris diaphragm restricts the diameter of the beam of light entering the objective and therefore excludes extraneous light to improve image contrast. It can be adjusted by moving the diaphragm control lever 3.

  • Brightfield Illumination
    Open the baffle by rotating the baffle control knob 4 counterclockwise. Inclusions should stand out as dark objects against a bright background.

  • Darkfield Illumination
    Close the baffle by rotating the baffle control knob 4 clockwise. The stone is illuminated with diffused light from the sides. View the stone against the baffle’s black, non-reflective background. Inclusions stand out as bright objects.

• Adjusting the Top Fluorescent Illuminator (Fig. 10)

  • By turning the main switch 5 to “I” (on) and the fluorescent lamp switch 6 to “I” (on), the top illuminator will provide the equivalent of a northern daylight overhead light source.

REPLACING THE LAMPS

Replacing the Halogen Lamp in the Bottom Illuminator (Fig. 11)

• The darkfield illuminator (bottom light) uses one 6 volt, 20 watt tungsten halogen lamp – CAT #6047C.
• To replace the lamp, tilt the Microscope all the way back (see page 8).
• On the bottom of the darkfield housing is a trap door. Open the trap door by loosening the screw (see Fig. 11). The screw can be loosened by hand or by using the small flathead screwdriver included in the original shipment of the Gem stand. The door will open and the lamp can be removed.
• IMPORTANT: When replacing the lamp, be careful not to touch the new lamp with your fingers as the oils and dirt on your fingers can affect the lamp’s performance. To insert the new lamp wrap the plastic bag supplied with the lamp or a piece of lens tissue around the lamp before handling/inserting it.

Replacing the Fluorescent Lamp in the Top Illuminator (Fig. 12)

• The fluorescent lamp in the overhead light uses one 7 watt fluorescent lamp – CAT #14120.
• To replace the lamp, disconnect the overhead light from the stage of the GEM stand base (see page 8).
• Remove the cover plate of the lamp housing by unscrewing the four screws on each corner of the cover plate using the Phillips head screwdriver that was included with your Gem stand.
• The fluorescent lamp is connected to a socket in the housing by a four pin connector. The socket is held in place with a screw. Remove the screw from the lamp socket.
• Carefully pull the fluorescent lamp out from the socket by the base of the lamp to avoid accidental breakage.
• Insert the new lamp into the socket and replace the lamp socket screw — be sure the lamp is securely in before replacing the cover plate on the lamp housing.
• Once the lamp housing is reassembled, reattach the overhead fluorescent light to the stage of the GEM stand base (see page 8).
