Description
The 90D Lens is an essential tool for ophthalmologists, designed specifically for detailed fundus examination using a slit lamp biomicroscope. This lens allows for comprehensive visualization of critical retinal areas, including the posterior pole, optic disc, macula, and retinal arcades. Its capability to perform effectively even through small or undilated pupils makes it invaluable for both routine and dynamic retinal assessments.
Optical Excellence
Crafted with a double aspheric design, the 90D Lens minimizes peripheral image distortion and enhances depth of field. This optical precision ensures clear and accurate retinal imaging, crucial for thorough examination. The lens provides an image magnification of 0.76x, complemented by the slit lamp's magnification, and a laser spot magnification of 1.32x, offering detailed insights into the retinal structure.
Field of View
The lens boasts a static field of view of 74°, expanding to 89° with a 15° tilt, allowing for extensive retinal coverage. Its non-contact design, maintaining a 7 mm working distance from the cornea, ensures patient comfort and ease of use during examinations.
Design and Material
With a typical diameter of 30 mm, the 90D Lens is easy to handle and manipulate within the orbit. Made from high-transmittance optical glass, it offers transmittance levels exceeding 95%, ensuring bright and clear images. Available in a variety of colors, this lens combines functionality with aesthetic versatility.
Versatile Use
The 90D Lens is widely regarded as the gold standard for slit lamp fundus examinations, suitable for both clinical and educational settings. It aids in the estimation of optic disc size and is compatible with most slit lamp biomicroscopes, making it a versatile addition to any ophthalmic practice.
Maintenance
Proper care involves cleaning with suitable lens solutions and storing in a protective case to prevent damage. Adhering to these guidelines will ensure the lens remains in optimal condition for long-term use.
Certifications
While specific certifications may vary by manufacturer, the 90D Lens typically aligns with standards such as CE, FDA, ISO13485, and RoHS, underscoring its quality and reliability in medical applications.
