    2. Zeiss
  2. Illumination Support
    1. Part
  3. Slit width Control
  4. Lmap husing unit
  5. Diffuser
  6. Prism
  7. Cobalt blue light
  8. Red free green filter
    1. helpful when viewing the bulbar conjunctiva, and episcleral blood vessels
    2. With the aid of the red free filter small hemorrhages, aneurysms and engorged vessels stand out

  17. Forehead band
  18. Lock for slit lamp base
  19. Power switch
  20. binocular eyepieces
    1. The eyepiece has a lens of +10 D
    2. it uses a pair of prisms between the objective and the eyepiece to reinvert image
  21. camera/video adaptor
  22. observation tube
    1. To provide good stereopsis, the tubes are converged at an angle of 10–15
  23. magnification changer
  24. Observation support
    1. Parts
  25. Notes
    1. composed of two optical elements – an objective and an eyepiece
    2. Objective lenses consists of two plano convex lenses, with their convexities put together providing a composite power of +22 D
  26. Mechanical Support

    2. Subtopic 3
  27. Uses
    1. a coupling of the microscope and the illumination system along a common axis of rotation which coincide their focal planes
    2. This ensures the light falls on the point where microscope is focused
    3. It allows either the microscope or the illumination system to be rotated around the axis without changing the focus
  28. This enhances fluorescein observations of the cornea and contact lens fitting
  29. A disadvantage of this filter technique is the high levels of illumination required because of the significant light losses in the filters and the relatively low level of ‘fluorescence’ being imaged
  30. Neutral density filter
    1. The use of a polarizing filter to remove glare is especially useful when photographing the aerial image of the fundus utilizing the slit lamp biomicroscope in conjunction with an attached camera
