The Huvitz Slit Lamp Microscope is a sophisticated ophthalmic instrument designed for detailed examination of the eye. It facilitates stereomicroscopic examination of the eye under slit light and microscopic examination of the ocular fundus and posterior vitreous body, often utilizing a Hruby's lens. This device is intended for use by ophthalmologists and optometrists.

Device Structure and Components:

The slit lamp is broadly divided into three main modules: the Microscope Module, the Illumination System, and the Mechanical Body.

Illumination System (HS-5000, HS-7000):

The illumination system is crucial for providing the necessary light for examination.

  • Light source: Halogen lamp (12V 30W) or LED.
  • Slit length: Adjustable from 0.3 to 12mm.
  • Slit width: Continuously adjustable from 0 to 12mm.
  • Slit projection: 1x magnification.
  • Aperture diaphragm: Multiple settings including 0.3, 1, 3, 5, 9, and 12mm.
  • Filters: Includes cobalt blue, ND (gray), heat absorption (IR), and red-free (green) filters.
    • Cobalt blue filter: Used with fluorescein dye for enhanced visualization.
    • Green filter (red-free): Obscures red elements, making blood vessels or hemorrhages appear black.
    • Neutral Density (ND) filter: Reduces the amount of light.
    • Heat absorption (IR) filter: Absorbs heat from the light source, protecting the patient's eye.
  • Slit rotation: Continuously adjustable from 0 to 180 degrees.

Illumination System (HS-5500, HS-7500):

This model includes additional features for enhanced illumination control.

  • Light source: Halogen lamp (12V 30W) or LED.
  • Slit length: Adjustable from 0.3 to 12mm.
  • Slit width: Continuously adjustable from 0 to 12mm.
  • Filters: Includes cobalt blue, ND (gray), heat absorption (IR), and red-free (green) filters.
  • Slit rotation: Continuously adjustable from 0 to 180 degrees.
  • Horizontal tilting: Allows for slit movement (left & right).
  • Vertical tilting: Enables angle change for the slit.
  • Diffuser: Used for diffusing the light, providing a broader, softer illumination.

Microscope:

The microscope module provides various magnification options and adjustments for optimal viewing.

  • Type: Galilean converging binocular (8°).
  • Eyepiece: Available in 12.5x and 10.0x.
  • Diopter adjustment: ±5D.
  • PD adjustment: Adjustable from 55 to 80mm.
  • Filter: Includes a yellow filter.
    • Yellow filter: Fits RGP lenses with fluorescein dye. It's important to check if the yellow filter is removed after installation if not needed.
  • Magnification: 5 positions rotating drum.
  • Total magnification & real field of view:
    • 6x (38.5mm)
    • 10x (22.2mm)
    • 16x (15.2mm)
    • 25x (10.5mm)

Maintenance Features:

Repair - Halogen Projection Bulb:

  1. Disconnect power.
  2. Remove screws (24) and cover (39).
  3. Remove socket from bulb stems.
  4. Rotate knob (54) to loosen bulb stopper.
  5. Remove the old bulb: Be cautious as it may be hot.
  6. Replace with a new 12V30W Halogen bulb: Use the plastic envelope and avoid touching the bulb with fingers.
  7. Fasten the bulb with the knob.
    • Warning: Do not touch the lamp house during operation as it heats up.

Repair - Fuse:

  1. Disconnect power.
  2. Remove the fuses housing.
  3. Replace the fuses.

Troubleshooting:

Not aligned focus between microscope and image:

  • Adjust diopters after setting a slit-lamp target.
  • Align camera focus using the 4.3F adjustment method.
  • Modifying the target's angle to about 45 degrees can improve focus clarity.
  • If problems persist, contact the agency.

Image is black out:

  • Check cable connection between camera and computer.
  • Verify proper camera driver installation.
  • Check camera selection option in the program (refer to software manual).

It doesn't capture the image:

  • Check proper joystick driver installation.
  • Verify joystick serial port setup on the computer (refer to S/W manual).
  • The joystick port is usually listed at the bottom of the software list.

The left and right movement was not realized:

  • The PCB ASSY (Z1_USB_JOYSTICK) has a location correction function using a PI Sensor.
  • Steps:
    1. Press the Joystick Button for 4 seconds.
    2. Move the Slit lamp from the far left to the far right.
    3. To exit the location correction function, click the Joystick Button again.
  • Notice: This function can be executed if power is supplied to the PCB ASSY (Z1_USB_JOYSTICK) and is irrelevant to the HIS program.

Computer can't realize the camera (USB and DSLR type camera):

  • This issue may occur with the latest iMac (2013) models with USB 3.0 ports.
  • Solution: Connect the camera and Slit Lamp Body to the computer using separate USB cables instead of a Y-cable. If using a Y-cable for the Slit Lamp Body and a USB cable for the HIS Camera, an additional USB cable is needed for the latest iMac (2013) models with USB 3.0 ports.
