Description
VolkUSA 20D Double Spheric Lens for Retinal Examination & Ophthalmic Diagnosis
The Volk USA 20D Double Spheric Lens is a high-magnification indirect ophthalmoscopy lens designed for retinal examination and ophthalmic diagnostic applications. Manufactured by Volk USA, this 20D lens provides a 2.97X magnification with a 47 mm working distance, making it suitable for detailed examination of the retina through a head-mounted binocular indirect ophthalmoscope (BIO).
The 20D configuration offers higher magnification than a commonly used 28D lens, making it particularly useful when greater retinal image detail is required. According to the supplied product information, it is especially suited to pediatric examination and situations where scleral indentation is required.
The lens is designed to provide a broad view of the retina, including peripheral areas, when used with a head-mounted BIO. Its glass construction and portable wooden case make it suitable for professional ophthalmic examination environments where a dedicated indirect ophthalmoscopy lens is required.
