Description

The 14D Lens is an essential tool for professionals in optometry and ophthalmology, designed specifically for binocular indirect ophthalmoscopy (BIO). This high-magnification aspheric condensing lens is crafted to provide detailed examination of the posterior pole, focusing on the macula and optic disc. Its application is invaluable in central retinal examinations, including glaucoma screening.

Key Features

• High Magnification: Offers enhanced observation capabilities for detailed retinal imaging.
• Aspheric Design: Minimizes aberrations and enhances imaging quality, with some models featuring computer-optimized designs for maximum resolution.
• Anti-Reflective Coating: Includes coatings such as Laserlight® HD to improve image contrast and reduce reflections.

Technical Specifications

• Field of View: Static range of 36°–38°, with dynamic capabilities up to 47°.
• Image Magnification: Between 4.17x and 4.30x.
• Working Distance: Approximately 72–75 mm.
• Lens Diameter: Around 52 mm, with a weight of about 57 grams.

Material and Build

Constructed from high transmittance optical glass, the lens features aspheric surfaces and specialized anti-reflective coatings. These materials ensure bright, clear images essential for accurate diagnosis.

Maintenance and Cleaning

Proper care involves using a low-foaming, neutral pH enzymatic cleaner at temperatures between 37–43°C. A soft-bristle brush and cotton cloth are recommended for cleaning, avoiding microfiber materials. Sterilization should be conducted using ethylene oxide (ETO), while avoiding autoclaving or boiling.

Storage Recommendations

For optimal storage, the lens can be kept either wet or dry, with dry storage recommended to reduce contamination risks. Cleaning with approved solutions and proper conditioning before use are advised.

Accessories

The lens typically includes a protective case, with options for custom engraving available. Proper alignment and positioning during use are crucial to minimize reflections and maximize the field of view.

This specialized lens is a reliable and durable choice for eye care professionals, offering precision and clarity in retinal examinations.
