With indirect ophthalmoscopy, the fundus is illuminated by light passing through the EDL-20D lens. The returning light then passes back through the EDL-20D to form a real, inverted image of the fundus between the lens and the practitioner.
The advantages of binocular indirect ophthalmoscopy compared to direct exams are the excellent, stereoscopic field of view and the ability to assess subtle diffuse fundus color changes.
The EDL-20D is made of high-transmittance glass to achieve distortion-free imaging. Users will obtain bright, clear images across the entire field.
The EDL-20D features a computer optimized aspheric design that minimizes reflections and delivers high-resolution images. A small holding ring also contributes to ease of use.
