Exam Principles: 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.
BIO Advantages: 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.
	Outstanding Optics: The EDL-20D is made of high-transmittance glass to achieve distortion-free imaging. Users will obtain bright, clear images across the entire field.
Unique Features: 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.
