Performance specifications

Performance specifications Functional description The SL 220 allows observation, diagnosis, measurement and documentation of the anterior eye segment, including the lens and vitreous body. The SL 220 is designed for the complete application area of a typical slit lamp. It is used by ophthalmologists, optometrists and opticians. The slit lamp consists of an instrument base (with joystick) onto which an illumination system (slit projector) and an observation unit (stereomicroscope with binocular tube and eyepieces) are mounted. The illumination system and the observation unit can be swiveled independently of each other around the same vertical axis. The head of the patient lies on the head rest. Using a fixation lamp, the user can direct the patient's eye as desired. The illumination system generates a slit image which can be modified in length, width, position and brightness and which has a specified distance from the slit lamp. The user can adjust each of the modifiable parameters of the slit image using the controls. The observation unit allows the user to observe the eye segment to be examined in selectable magnification steps. The magnification changer is a Galilean system with telecentric beam path. The user can position the slit lamp in relation to the examined object in all three axes using the joystick of the instrument base so that the desired observation area of the eye is in focus. Using different illumination methods, variable slit images and filters, it is possible to view almost all eye segments. The SL 220 can be enhanced by optional accessories. With the AT 030 applanation tonometer the user can measure the intraocular pressure. The SL Imaging Solution imaging accessory for slit lamps enables images and videos of the anterior segment of the eye to be acquired for documentation purposes.
