The e-scope Ophthalmoscope is a powerful and reliable instrument for efficient fundus examination in clinical practice. The innovative 3.7 V LED illumination delivers high contrast and true-to-life colour rendering, supporting confident diagnostic decisions. With a service life of up to 20,000 hours, the LED system reduces maintenance requirements and ensures consistent performance in routine use. The aspherical condenser lens system provides sharp, collimated light while minimising reflections, enabling clear and accurate assessment of the fundus even under challenging examination conditions. The dioptre wheel with 18 correction lenses (±1, 2, 3, 4, 6, 8, 10, 15, 20 dioptres), combined with an intuitive aperture system (4 apertures and 2 filters including fixation star, large circle, small circle, semicircle, blue filter, and red-free filter), allows precise adaptation to different clinical needs. Its compact, lightweight design makes the ophthalmoscope ideal for mobile use and daily clinical workflows. A spectacle guard enhances patient comfort and safety during examination. The dust-protected housing and robust construction ensure long-term durability, even with frequent transpo
