  • Page 19: Checking Procedure

    CHECKING PROCEDURE (1) Power Plug * Make sure that the instrument is always properly grounded. (2) Illumination and Instrument Functions * Turn the power supply on and observe that the illumination is passing through the opened slit controls. * Check to insure that the fixation device is illuminated. * Check to see that the slit width and length controls, filter lever and magnification changer lever operate smoothly and properly.

  • Page 20: Operation Procedures

    OPERATION PROCEDURES PREPARATION-DIOPTER COMPENSATION AND INTERPUPILLARY DIS- TANCE ADJUSTMENT Before using the instrument, always carry out the diopter compensation and interpupillary distance adjustments. (1) Use of the focusing test rod The focusing test rod, which is a standard accessory, is used to establish the proper micro- scope settings for each use.

  • Page 21: Patient Position And Fixation Target

    * Follow the same procedure for the other ocular. Diopter scale * Denote the diopter values on each ocular for future reference. (4) Interpupillary distance adjustment While looking through the eyepieces at the image on the focusing test rod, adjust the converg- ing binocular's prism box, so that the image is fused and a stereoscopic image results.

  • Page 22: Base Operation

    (2) To establish patient fixation To maintain patient fixation, have the patient observe the fixation target with the eye not being tested. To alter fixation, move the position of the target by the fixation target lever. The fixation target, which allows diopter compensation, provides a dot and a concentric circle target.

  • Page 23: Operation Of The Illumination Unit

    (5) Focusing * Gross adjustment for alignment or focusing is done by the operation described in (1) * Fine adjustment for alignment or focusing should be done by the operations described in (2) and (3) above while looking through the microscope. OPERATION OF THE ILLUMINATION UNIT (1) Altering the slit size By operating the slit width control knob, the slit width can be changed from 0 to 9mm (at the...
  • Page 24 (2) Changing aperture and slit length By operating the aperture and slit length control knob, 7 different circular beams of light are available at full aperture: 9, 8, 5, 3, 1, and 0.2mm dia. With a slit image, the slit length can be changed continuously from 1 to 8mm with this knob.
  • Page 25 (4) Decentering the slit beam With the Model SL-3E, the illumination can be moved from the parafocal position with the microscope by loosening the centering control. The illuminated image then would move away from the center of the microscope's field of view. It is of particular benefit in indirect retro-illu- mination techniques.
  • Page 26 (6) Reflection mirror Two mirrors are supplied with the SL-3E. One is a long mirror and the other is a short mirror which has no protruding surfaces. Usually, for most examinations, the long mirror is used. However, when the angle between the illumination unit and the microscope is within approxi- mately 3°...

  • Page 27: Fundus Observation With The Hruby Lens (Option)

    FUNDUS OBSERVATION WITH THE HRUBY LENS (OPTION) In routine applications, only the anterior segment of the vitreous body can be examined because of the refraction effects of the cornea and crystalline lens. However, with the Hruby Lens, exami- nation of the fundus and the posterior segment of the vitreous body is possible. Operation procedure: (1) The pupil should be well dilated by administering a mydriatic approximately 20 minutes before the examination.
