32-709 18mm Dia. x 36mm FL Uncoated; Double-Convex Lens

The 32-709 is a high-quality spherical lens, boasting a double-convex design and a sizable 18mm diameter. This lens is sourced from the renowned optical vendor, Edmund Optics, and is available for purchase directly from their website. The lens is currently in stock, ensuring quick and efficient procurement for your optical project needs.

The lens's focal length is 36mm, making it a versatile option for a variety of applications. The double-convex shape, characterized by two convex surfaces, provides a unique optical profile. This shape is often utilized in optical systems to focus or collimate light. The lens's base shape is circular, contributing to its robust optical performance.

The lens's geometry is meticulously crafted, with a thickness of 2.55mm at the edge and 4.8mm at the center. The effective focal length (EFL) is 36mm, and the back focal length (BFL) is 34.59mm. The first radius of curvature (R1) is 36.6mm, while the second radius (R2) is -36.6mm, indicating the double-convex design. The inner and outer radii are both 0, suggesting a uniform curvature throughout the lens.

The lens is made from n-BK7 Schott, a high-grade optical glass known for its excellent optical properties. The lens is uncoated, offering bare glass surfaces that can be utilized as is or coated according to specific project requirements.

The lens is designed to work with a wavelength of 587.6nm, making it suitable for applications that operate within this wavelength range. This lens is a fantastic option for those seeking a reliable, high-performing spherical lens for their optical projects.
