The slit lamp’s design integrates several key components that work in harmony to facilitate detailed ocular examination. The slit lamp or biomicroscope is an instrument designed primarily to observe the transparent structures of the human eye under a magnification of between 10 to 50 times. Its two principal parts include a lamp equipped with an optical system designed to project a slit of light upon the eye, and a stereomicroscope which is mounted horizontally for direct viewing of the patient’s eye. The slit lamp may be adjusted to project a variety of light beams.
Slit Lamp
Overview
Core Features
- Stereoscopic Vision: Binocular eyepieces provide depth perception (3D view) of eye structures.
- Adjustable Slit Beam: A bright light source projects a narrow, controllable slit (height, width, angle) for optical slicing of eye tissues.
- Magnification: Offers varying magnification (e.g., 10x, 16x, 25x, 40x) for detailed observation.
- Illumination System: Uses LED or Xenon bulbs with different techniques (direct, indirect, retroillumination).
