33-395 25mm Dia. x 200mm FL; MgF2 Coated; Double-Convex Lens MgF2 400-700nm

This is a high-quality double-convex lens, sourced from the renowned optical component vendor, Edmund Optics. The lens, identified as the 33-395, boasts a diameter of 25mm and a focal length of 200mm, making it a versatile choice for various optical applications.

The lens is crafted from n-BK7 Schott, a popular optical glass due to its excellent optical properties and high Abbe number. This material ensures high transmittance and low dispersion, making it ideal for imaging and beam manipulation applications.

The lens features a front and back coating of edm mgf2 std curve. This MgF2 coating enhances the lens's performance by reducing surface reflections, thereby increasing transmission and minimizing lens flare. The coating is designed to operate within the wavelength range of 400-700nm, making it suitable for a broad spectrum of applications, including visible light imaging and laser systems.

The geometry of the lens is meticulously designed, with an edge thickness of 4.24mm and a center thickness of 5mm. The lens's front and back radii are R1 = 205.865mm and R2 = -205.865mm, respectively, while the back focal length is 198.35mm. These parameters contribute to the lens's high-performance optical characteristics.
