84-309 15mm Dia. x 45mm FL VIS 0deg Coated; UV Plano-Convex Lens VIS 0° 425-675nm

The 84-309 is a 15mm diameter, 45mm focal length Plano-Convex lens, specifically designed for visible light applications with a wavelength of 587.6nm. Sourced from Edmund Optics, this lens is made from fused silica (mal-1965) and features a standard curve coating on both the front and back surfaces, enhancing its performance in various applications.

The lens's geometry includes a 1.59mm edge thickness and a 3mm center thickness, providing a robust structure suitable for diverse optical systems. Its base shape is circular, and the lens is spherical, ensuring excellent light transmission and focus. The inner and outer radii are both zero, indicating a uniform curvature across the lens surface.

The 84-309 has a 42.94mm back focal length (BFL), which is the distance from the lens's rear surface to the focus point. This information is crucial when designing an optical system, as it helps determine the positioning of other components in the system.

This lens is designed to transmit light within the visible spectrum, specifically between 425 and 675nm. This makes it suitable for a wide range of applications, including imaging, illumination, and metrology systems.
