Features of the EDL-20D ▪ Outstanding Optics ▪ Computer Optimized Aspheric Design ▪ Distortion-Free Imaging ▪ High-Transmittance Glass ▪ Small Holding Ring
		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.
