This is a Plano-Convex lens, a type of spherical lens, sourced from Holmarc Opto-Mechatronics. With a base shape of a circle, it has a diameter of 30mm and a thickness at the edge of 2mm. The effective focal length (EFL) of this lens is 250mm, making it suitable for various optical applications.
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-convex geometry where one side of the lens is flat, and the other side is curved. The radius of curvature of the curved side is 130.404mm.
This lens is designed to operate at a wavelength of 587.6nm. It does not come with any coating, which means it is uncoated. However, users can request coatings based on their specific requirements.
