ABSTRACT:
The invention contemplates slit-lamp apparatus for ophthalmological examinations and is characterized by simplicity of components designed to facilitate use, the use being assumed to involve the analytical operations most often needed. The instrument is portable and provides ready availability of slit-projector means and tonometer means when desired, on the microscope-viewing axis. All components are upstanding, with respect to the mounting base, and simple knurled-ring adjustments enable selection of projected-slit dimensions and filters.
