1. Two eyepiece barrels with LED illumination. Each barrel can accommodate 2 lenses, allowing selection of appropriate magnification lenses based on the size of the observed object.
2. 10 magnifying lenses (5 different magnifications) for installation in the left and right barrels, enabling multiple magnification combinations. Offers 12 magnification combinations, with maximum magnification reaching up to 23x.
3. The LED lamps can be fitted with two interchangeable diffusers of different color temperatures, providing 6 lighting options for observing small objects: a) low cool light, b) strong cool light, c) low soft warm light, d) strong soft warm light, e) low deep warm light, f) strong deep warm light. This offers an optimal working environment.
4. The nose bridge utilizes stainless steel and soft rubber via a two-shot molding process. It can be freely adjusted to fit different nose shapes.
5. Equipped with high-efficiency rechargeable lithium batteries. A full charge takes only 1.5 hours, significantly extending LED operating time. Eliminates the hassle of frequent battery changes and offers greater cost-effectiveness.
6. Features a separate LED lamp and control switch design. The two control switches are conveniently located on the forehead, allowing easy operation without accidentally touching the lamps and altering the light angle, thus reducing the need for readjustments.
7. Adjustable eyepiece angle and LED illumination angle ensure precise light projection onto the target surface. When not in use, the entire eyepiece and light assembly can be flipped up onto the forehead, eliminating the need for frequent removal of the magnifier.
