This is a Plano-Convex lens, a type of spherical lens, sourced from EKSMA Optics. The lens has a base shape of a circle and a diameter of 25.4 mm. The thickness at the edge of the lens is 2.9 mm, while the thickness at the center is 3 mm. The effective focal length (EFL) of the lens is 3000 mm.
The lens is made of BK7 Schott, a popular optical glass known for its excellent optical properties. The radius of curvature for the first surface (R1) is 1556.2 mm, while the inner and outer radii are both 0 mm.
This lens is coated with EKS 3217-i0 on both the front and back surfaces. This coating is designed to provide anti-reflection properties within the wavelength range of 400-700 nm.
