Product Description
The LS-4 Ophthalmic Slit Lamp Microscope is a high-performance instrument with a parallel Galilean optical system, delivering clear stereoscopic binocular fusion. Featuring a revolving drum magnification changer with 5-step magnification (6x to 40x), it ensures precise observation for a wide range of clinical applications.
Equipped with a warm LED light source rated for 20,000 hours, and PMW (Pulse Width Modulation) control, the LS-4 provides stable, continuous illumination that is gentle on eye tissues. The device also allows optional upgrades to a teaching slit lamp or a digital imaging system, offering excellent flexibility for modern practices.
