3.7 Functional description
The slit lamp consists of an instrument base with joystick onto
which a slit projector (serving as illumination unit) and a stereo-
microscope with binocular tube and eyepieces (serving as obser-
vation unit) are mounted. The headrest is used to position the
patient's head. The slit projector generates a slit image at a
specified distance from the slit lamp (focus plane). The user can
variably adjust the width, length, position and brightness of the slit
image by means of appropriate control elements and filters. The
observation unit allows the user to view the eye structure in various
magnification steps. The user can position the slit lamp in all three
axes using the joystick of the instrument base so that the eye
structure is in focus. The slit lamp can be extended with optional
components and accessories, e.g. for image documentation or for
measuring intraocular pressure.
