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 30mm. The thickness of the lens at the edge is 2.5mm. The effective focal length (EFL) of this lens is 50mm, making it a high-quality lens 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 radius of the lens is 0mm, and the outer radius is also 0mm, indicating a plano surface on one side and a curved surface on the other. The curvature of the curved surface is such that the radius of curvature (R1) is 26.081mm.
This lens is designed to operate at a wavelength of 587.6nm. It does not have any coating, which means it is uncoated. However, this does not affect its optical performance significantly, especially in applications where coating is not a critical factor.
