Description
Indigenous 20D BIO Lens for Retinal Examination & Indirect Ophthalmoscopy
The Indigenous 20D BIO Lens is a high-magnification ophthalmic diagnostic lens designed for use with a binocular indirect ophthalmoscope (BIO). It provides a practical balance between retinal magnification and field of view, making it suitable for general retinal examination as well as detailed central retinal assessment.
With a 3.13X image magnification, 46°/60° field of view and 50 mm working distance, the 20D lens is designed to provide a comfortable working distance while allowing the clinician to examine the retina through a head-mounted BIO. Its combination of magnification and field coverage makes it suitable as a first-line retinal examination lens and for more detailed central retinal evaluations.
The lens follows the double-aspheric lens design tradition associated with 20D BIO lenses and is intended to provide clear retinal visualisation during indirect ophthalmoscopy. The supplied specifications also identify a 0.32X laser spot magnification, which can be relevant when the lens is used in appropriate retinal laser examination or treatment workflows.
For ophthalmologists, retinal specialists, eye hospitals and ophthalmic diagnostic practices, the Indigenous 20D provides a versatile option for routine retinal examination where both magnification and field of view are important.
