When used with a compatible binocular indirect ophthalmoscope, slit lamp, or examination illumination system, it provides a clear stereoscopic view of retinal structures.

Its 20-diopter optical power offers a practical balance between image magnification, field of view, and working distance, making it suitable for routine ophthalmic examinations in clinics, hospitals, universities, and mobile eye-care environments.

Outstanding Features

20D Indirect Diagnostic Lens

The INS-11075-1 features a 20-diopter optical power commonly used for indirect examination of the retina and posterior segment.

Wide-Angle Retinal Observation

A 50° field of view allows the practitioner to observe a broad retinal area during examination.

2.97× Image Magnification

The lens provides approximately 2.97× image magnification, supporting clear visualization of retinal details and posterior-segment structures.

Comfortable Working Distance

A working distance of approximately 47 mm provides practical separation between the lens and the patient’s eye during examination.

Non-Contact Examination

The lens is designed to provide retinal visualization without contacting the patient’s eye, supporting patient comfort and efficient clinical workflow.

Stereoscopic Visualization

When used with compatible binocular observation equipment, the lens supports a three-dimensional view of the fundus for improved evaluation of retinal structures.

Clear 48 mm Aperture

The lens incorporates a 48 mm clear aperture within a 50 mm lens diameter for a broad and unobstructed viewing area.

Durable Three-Part Construction

The indirect diagnostic lens consists of the optical lens, protective holder, and fixed retaining ring for secure handling during examinations.

Compact and Portable

Its lightweight construction makes the lens easy to carry between examination rooms, outreach programs, and mobile eye-care locations.
