This is a Plano-Convex lens, a type of spherical lens with a flat surface and a curved surface. The lens has a base shape of a circle and a diameter of 30mm. The thickness of the lens at the edge is 2.5mm, and it has an effective focal length (EFL) of 50mm.
The lens is made of N-BK7, a type of glass commonly used in optical systems due to its excellent optical properties. The inner and outer radii of the lens are 0, indicating a plano surface on one side and a curved surface on the other. The curvature of the curved surface is defined by a radius of 26.081mm.
This lens is designed for use in the wavelength range of 587.6nm, which is in the visible light spectrum. It is coated with BBAR (Broadband Anti-Reflection) coating, which reduces reflection and increases transmission of light over a broad spectrum (400-700nm). The BBAR coating is applied to both the front and back surfaces of the lens.
The lens is sourced from Holmarc Opto-Mechatronics, a reputable vendor known for its high-quality optical components. According to the vendor's website, the lens is in stock, ensuring quick delivery.
