The 84-207 is a Plano-Convex Spherical Lens, a high-quality optical component designed for use in laser systems operating at a wavelength of 1550nm. This lens is sourced from the renowned optical vendor, Edmund Optics, and is available for immediate purchase, as indicated by its "in stock" status on the vendor's website.
The lens features a base shape of a circle, with a diameter of 6.0mm and a thickness of 0.95mm at the edge, transitioning to a center thickness of 1.75mm. The effective focal length (EFL) of the lens is 9.0mm, making it suitable for applications requiring a long focal length. The lens's front and back surfaces are coated with Edmund Optics' Laser V-Coat, specifically designed for 1550nm, ensuring high transmission and low reflection.
The lens is made from n-SF5 Schott, a material known for its excellent optical properties, including high transparency and low dispersion. The lens's geometry, including its inner and outer radii, is optimized for use in laser systems, ensuring minimal aberration and distortion.
