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 38.1 mm. The thickness at the edge of the lens is 2.6 mm, while the thickness at the center is 4 mm. The effective focal length (EFL) of the lens is 250 mm.
The lens is made of BK7 Schott, a popular optical glass known for its excellent optical properties. The front and back of the lens are coated with eks ar532, an anti-reflective coating designed for a wavelength of 532 nm. This coating helps to reduce unwanted reflections and increase the transmission of light through the lens.
The lens is a Spherical type, which means it has a spherical surface. The first radius of curvature (R1) is 129.7 mm. The inner radius and outer radius are both 0 mm, indicating that the lens does not have any additional curvatures.
