SLM-4 five-step magnification slit lamp (6×–40×) with LED illumination — the workhorse anterior-segment biomicroscope for general ophthalmology clinics.
Clinical overview
The OpticsMED SLM-4 steps up the SLM line to five magnifications (6×, 10×, 16×, 25×, 40×), giving the ophthalmologist a low-power wide-field for orientation and a 40× detail step for endothelial-cell and crystalline-lens grading. The five-position drum is the configuration most ophthalmology trainees are taught on, so the SLM-4 lands in fellowship-trained practices without a workflow surprise.
| Magnification | 6×, 10×, 16×, 25×, 40× |
|---|---|
| Field | Ø 37, 23, 14, 8.7, 5.7 mm |
| Slit width | 0 – 14 mm continuous |
| Filters | Heat, grey, red-free, cobalt blue |
| Power | 110/110V/220V ±10 %, 60 VA |
General ophthalmology clinics and refractive surgery practices that need the full five-step magnification range for inspection / measurement workups. Particularly suited to fellowship-trained practices that want a familiar workflow without paying for the SLM-6's integrated imaging system.
