Slitlamp Microscopes MS-103
Slitlamp Microscopes · Model MS-103
OPHTHALMOLOGY SLIT LAMP MICROSCOPE This is a slit lamp microscope used by ophthalmologists in the field of ophthalmology for eye examination. The magnification is selectable between 6x, 10x, 16x, 25x, and 40x. The included eyepiece pair is 12.5x. It comes with optional R and T type applanation tonometers as well as an optional measuring eyepiece. Another option is a beam splitter, ccd camera adapter, and ccd camera for taking the video image to a cctv monitor for all in the room to see, or for the ophthalmic examination to be videotaped. Another useful option is an extra monocular teaching tube, allowing a third observer/assistant to view the ophthalmic eye examination simultaneously. The lens is made from high quality imported German glass for reduction in lens aberration. All optics are multi-coated and include mildew-proof and antireflection coatings. This slitlamp microscope is made in a US FDA (Food and Drug Administration) registered manufacturing facility as well as has CE certification.
Typical Failure Modes
Compiled for this model from its own documentation and established engineering knowledge for this equipment class - not from a verified service record. Confirm against the manufacturer's service manual.
Illumination lamp failure or dim / uneven slit
HighSymptoms: No or dim slit, uneven illumination, colour shift.
Root cause: Halogen / LED source at end of life, a bulb-holder / contact fault, or a rheostat fault.
Slit / aperture / filter mechanism fault
MediumSymptoms: Slit width, length, angle or filter selection will not change or sticks.
Root cause: Worn slit mechanism or filter turret.
Joystick / base motion fault
MediumSymptoms: Coarse or fine movement binds, drifts, or the locking screw is ineffective.
Root cause: Dry or worn base slide / bearings, or a loose locking screw.
Optics contamination
LowSymptoms: Haze, spots, or reduced image quality through the oculars.
Root cause: Dust or fingerprints on the objective, oculars, or mirrors.

Troubleshooting Approach
A starting sequence for this model, compiled from its documentation and engineering knowledge for this equipment class. Follow the manufacturer's service documentation for the actual procedure.
Symptom: No or dim slit
- Replace the source (let it cool first) and check the bulb-holder contacts.
- Operate the rheostat through its range for a dead spot.
- Check the mains fuse (unplug first).
- Confirm even slit illumination at full and low intensity.
- Clean the projection optics and mirror.
Symptom: Base or joystick motion binds
- Confirm the locking screw is released.
- Clean the base glide plate and lightly lubricate per the manual.
- Check the bearings / slide for wear or debris.
- Replace worn base-slide bearings.
- Confirm smooth coarse and fine movement and a firm lock.
