1. Optical Fiber
This optical fiber connects between the Slit lamp LDU and the Laser Console. The
treatment laser and aiming beams are focused into the fiber.
2. Zoom System and TruScan Housing
This is where the pattern generated through the two high speed scanning motors.
Also, the laser beams spot size to be adjusted through this zoom pc range from 50
to 1000 m by rotating the control. This spot size is reflected in the pattern control
screen.
3. Objective focus lens
This is part of the Slit lamp unit and the Laser beams are also focused by this lens to
the treatment site. The focus length is 117mm.
4. Magnifier Control
The magnification as seen by the doctor is adjusted using this control. The selected
magnification is shown on the knobs. A larger magnification will give a larger image
of the treatment site.
5. Binocular and eyepieces
The doctor looks through the eyepieces to view the patient. The Interpupillary
Distance can be adjusted as well as the individual’s Diopter settings for each
eyepiece.
6. Doctor Safety Filter
This safety filter is a standard set-up in every Slit lamp LDU and is located at
microscope housing. This filter will prevent back reflections during laser treatment
which may cause injury to the doctor’s eyes. Usually the filter is a fixed optic lens
however it is also an option to install a moving filter. The orange filter provides
protection >OD4 @ 532nm Single-Wavelengthnm
7. Focus Set Screw
This screw is used to set the viewing focus of the microscope to be in sharp focus on
the Target Rod. Tightening this screw into the housing, the focus point is moved
away from the Target rod and it is towards the user. Loosening this screw and then
pushing the microscope housing up firmly against the screw sets, the focus more
towards the patient.
Slit lamp LDU system can be integrated with two types of the slit lamp that carry by
Lightmed are as:
CSO SL980 (Integrated with Slit lamp)
