Product Overview
Welch Allyn - 11875 - Accessories: Corneal Lens
The Welch Allyn Corneal Lens (Model 11875) features patented Axial PointSource Optics, delivering superior illumination and clarity for retinal examinations. The illumination system converges light to a precise point at the cornea, facilitating entry into small, undilated pupils, then diverges to illuminate a wide area of the fundus. The viewing system aligns with the illumination axis, providing an expansive field of view.
Key Features:
- Wider Field of View: Offers a five-times larger view of the fundus compared to standard ophthalmoscopes in undilated eyes.
- Enhanced Magnification: Increases magnification by 26% over conventional ophthalmoscopes.
- Glare Reduction: Patented Glare Extinguishment System minimizes unwanted reflections for clearer imaging.
- Compatibility: Works with all Welch Allyn 3.5V power sources (battery handle or wall transformer).
- Patient Eyecup: Maintains proper viewing distance, stabilizes the exam, occludes ambient light, and aids in orientation.
- Dynamic Focusing Wheel: Smoothly adjusts focus (-20 to +20 diopters) for precise control.
- Aperture Dial: Includes micro, small, and large spot sizes, slit aperture, red-free filter, and cobalt blue filter (Model 11820 only).
Specifications:
