This is a Plano-Convex lens, a type of spherical lens, sourced from Holmarc Opto-Mechatronics. The lens has a base shape of a circle and a diameter of 50mm. The thickness of the lens at the edge is 3mm, and it has an effective focal length (EFL) of 80mm. The lens is made of n-BK7 Schott, a popular optical glass known for its excellent optical properties.
The lens is designed to work with a wavelength of 587.6nm. It features a Broadband Anti-Reflection (BBAR) coating on both the front and back surfaces, which enhances its transmission capabilities within the 400-700nm wavelength range. This coating reduces reflection and increases the amount of light that passes through the lens, making it suitable for various applications.
Please note that the inner and outer radii of the lens are 0, indicating that it is a Plano-Convex lens with a flat plane on one side and a curved surface on the other. The curvature of the curved surface is specified by a radius of 41.729mm.
This lens is currently in stock and available for purchase through the Holmarc Opto-Mechatronics website.
