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. The effective focal length (EFL) of this lens is 400mm, making it suitable for applications that require a longer focal length.
The lens is made of N-BK7, a type of glass commonly used in optical applications due to its excellent optical properties. The inner radius of the lens is 0mm, and the outer radius is also 0mm, indicating that the lens is plano-convex in shape, meaning one side is flat, and the other side is curved.
The wavelength for this lens is 587.6nm. The lens does not come with any coating, as indicated by the empty 'coating' field in the item data. This means that the lens will not have any additional protective or enhancing layers, which could affect its performance in certain applications.
The lens is in stock and available for purchase, as indicated by the 'weblink status' field in the item data. For more information, you can refer to the vendor's website through the provided weblink.
