The Slit Lamp Step-3 (ZEISS & HAAG models) is a precision ophthalmic diagnostic instrument designed for detailed anterior segment examination. Built with a robust yet compact structure, it features a 3-step magnification system (10x, 16x, 25x, and 40x with 10x eyepiece), enabling clinicians to perform accurate and comfortable eye evaluations. The system supports dual illumination options—LED or Halogen, ensuring consistent brightness and optimal contrast. Integrated filters including Cobalt Blue, Red-Free (Green), Heat Absorbing, and Diffuser enhance diagnostic clarity across multiple examination needs. The slit width and length are continuously adjustable, with full 0°–180° slit rotation and multiple inclination angles for flexible observation. Ergonomically designed components such as the joystick control, chin rest, forehead rest, and canthus alignment provide smooth operation and patient comfort. With a universal power supply and lightweight design, the Step-3 Slit Lamp is ideal for clinics and hospitals seeking reliability, precision, and ease of use.
