This is a Plano-Convex Lens, a type of spherical lens, sourced from Standa. The lens has a base shape of a circle and is designed for use in the visible light spectrum, specifically at a wavelength of 546 nm.
The lens has a diameter of 25.4 mm and a thickness at the edge of 2.8 mm. The thickness at the center of the lens is 3 mm. The effective focal length (EFL) of the lens is 700 mm. The radius of curvature (R1) of the curved surface is 361.69 mm, while the inner and outer radii are both 0 mm, indicating a plano surface on the other side.
The lens is made of n-BK7 Schott, a common optical glass known for its excellent optical properties. The lens is uncoated, meaning it does not have any additional layers to enhance its optical performance or protect it from environmental factors.
