Universal slit lamp with pioneering features

Sharp optics combined with bright, homogeneous slit illumination guarantees you a clear view with the OCULUS SL-IC4 and SL-IC5. Take advantage of the wide range of filters (blue, red-free, neutral density, diffuser) integrated in the new OCULUS slit lamp to improve the quality of your examination results. Its no-hassle controls allow you to focus entirely on the examination.

Advanced optics with a magnification range from 6x to 40x

Stereomicroscope with convergent binocular tube and smooth-switching five-step magnification changer from 6x through 40x (6x, 10x, 16x, 25x, 40x). Integrated in the microscope is also a yellow filter which can simply be interposed when needed.

LED illumination

Bright, homogeneous and economically efficient. These carefully selected LED modules guarantee you the very best lighting conditions as well as durability.

Available in two models:

OCULUS SL-IC4 with a compact design
OCULUS SL-IC5 with a slim, tall design

„Digital ready” – easy to upgrade to a photo slit lamp!

Both slit lamp models are available in a “digital ready” version. The OCULUS SL-IC4 D and SL-IC5 D both come with a digital port for connection to the OCULUS image documentation system ImageCam® 2. Images and videos can be conveniently captured by joystick rather than with the foot switch.

Optional accessories

  • Various matching applanation tonometers for numerous popular slit lamps of most manufacturers.
  • Diagnostic contact lenses for inspecting the anterior chamber angle and the posterior eye segment.
  • Elbow support
  • Ergonomic eyepiece adapter 20°
  • Eyepiece with length and angle scales

Equipment table

With either model, if the OCULUS slit lamp is not to be mounted on an existing examination unit, it can be delivered mounted on a small equipment table with integrated chin and head rests. Alternatively with large instrument table and HP computer.

Decoupling Function

Both models have a decoupling function as a standard feature.
