Condition & Warranty
Used. This Carl Zeiss 30 SL-M slit lamp has been fully tested and is in excellent working order. The legendary Zeiss optics are crisp and free of delamination, the illumination system is bright and steady, and all mechanical adjustments — including the joystick and elevation controls — glide smoothly. The unit shows signs of use consistent with a used clinical instrument. Carefully tested before shipping. Covered by a 90-day warranty on parts and workmanship.
Carl Zeiss 30 SL-M — Used Slit Lamp with Precision Zeiss Optics
The Carl Zeiss 30 SL-M is a durable, classic tabletop slit lamp renowned for its superb mechanical stability and optical clarity. Featuring a 5-step Galilean magnification changer (6×, 10×, 16×, 25×, and 40×), its parallel optical system lets ophthalmologists and optometrists transition seamlessly from wide-field structural overviews to high-power cellular inspection of the anterior segment.
Built to withstand decades of heavy clinical use, the 30 SL-M employs a high-performance halogen illumination column that delivers a sharp, homogeneous slit image. Slit width, length, and rotation are fully adjustable, and the integrated filter wheel provides standard diagnostic options. With a responsive single-handed joystick for precise tracking, this used Zeiss slit lamp remains a dependable fixture for everyday eye examinations.
The conventional slit lamp is still the benchmark that new anterior segment imaging devices are measured against — a 2026 study indexed by the National Library of Medicine compared a mobile imaging device with conventional slit-lamp imaging for cataract photography.
Why Practices Choose the Carl Zeiss 30 SL-M
- Legendary Zeiss Optics — exceptional depth of field, maximum light transmission, and razor-sharp resolution for accurate diagnostic visualization
- 5-Step Magnification Changer — switches between 6×, 10×, 16×, 25×, and 40× click-stops to match each exam
- High-Contrast Halogen Illumination — a warm, uniform beam that ensures natural tissue color and comfortable patient viewing
- Precise Joystick Control — single-handed mechanical alignment with micro-precise adjustment over horizontal, vertical, and cross-slide axes
- Versatile Slit Adjustments — continuous slit width from 0 to 9 mm and selectable slit lengths from 0.3 to 9 mm for detailed optical sections
- Robust Mechanical Reliability — all-metal chassis prevents alignment drift for long-term consistency in high-volume lanes
- Integrated Filters — cobalt blue, green (red-free) and a diffusing screen for fluorescein staining, vascular checks and diffuse illumination
Clinical Applications
- Comprehensive Anterior Segment Evaluation — detailed inspection of the cornea, iris, conjunctiva, and crystalline lens
- Contact Lens Management — evaluating fit, centration, movement, and corneal response under fluorescein illumination
- Foreign Body Removal — the magnification and mechanical stability required for delicate corneal procedures
- Applanation Tonometry Workstation — pairing with a standard Goldmann tonometer for accurate intraocular pressure checks
Who This Is For
- Private Practice Optometrists and Ophthalmologists — seeking world-class optical performance at a fraction of new-equipment cost
- Satellite Offices and Secondary Lanes — needing a reliable, durable backup biomicroscope for general patient flow
- Surgical Pre-Op Lanes — requiring quick, crisp structural confirmation before specialized testing
