Description
The Topcon SL-2G is a refined yet economical slit-lamp biomicroscope designed for general ophthalmic and optometric use, offering reliable performance, modern LED illumination and Topcon’s hallmark optical clarity. At its core, the SL-2G utilises a Galilean (converging) binocular microscope system paired with a 3-step magnification drum (10×, 16×, 25×) and a long-life LED light source that enables routine anterior segment examination with minimal maintenance.
This model is engineered for the budget-sensitive clinic that still demands optics that deliver crisp, distortion-free views of the cornea, anterior chamber, iris and lens. The LED illumination is not only energy-efficient and low-heat but also offers a uniform beam, consistent color rendition and approximately 10,000 hours service life—up to 100 times longer than typical halogen lamps.
Operator ergonomics and workflow are addressed with a large slit width range (0-14 mm), slit-length control, aperture diaphragm selections, slit-angle rotation from 0° to 180°, built-in cobalt blue and red-free filters for fluorescein and vessel/nevi contrast exams, and optional accessory mounts (e.g., applanation tonometer).
In short, the SL-2G combines cost-effectiveness, contemporary illumination technology, proven optics and a flexible feature set—making it a strong choice for busy clinics or practices looking to equip an exam lane with a dependable slit lamp while maintaining quality and longevity.
