63-831 12mm Dia. x 30mm FL; VIS-NIR Coated; UV Double-Convex Lens VIS-NIR 400-1000nm

The 63-831 is a high-quality double-convex lens, sourced from the renowned optical components manufacturer, Edmund Optics. This lens boasts a 12mm diameter and a 30mm focal length, making it suitable for a wide range of applications that require precise optical focusing.

The lens is constructed from fused silica, a material known for its excellent optical properties, including high transparency across a broad spectrum. This particular lens is designed to transmit light in the visible (VIS) and near-infrared (NIR) ranges, specifically between 400 and 1000 nanometers. This makes it a versatile choice for applications in fields such as biomedical imaging, machine vision, and spectral analysis.

The 63-831 lens features a unique spherical geometry, with both surfaces curved outward. This design, combined with the lens's high refractive index, allows for efficient light bending and focusing. The lens's geometry also includes an inner radius of 0 and an outer radius of 0, indicating a symmetrical design that can help minimize optical aberrations.

The lens is coated with a VIS-NIR coating, denoted as 'edm visnir0sp2002000' on both the front and back surfaces. This coating is designed to enhance the lens's performance in the VIS-NIR range by reducing surface reflections and increasing transmission. The coating also provides protection against environmental factors that could potentially degrade the lens's optical performance over time.
