110-0285E+3217-i0 25.4 mm Dia. x 4000 mm FL Plano-Convex Lens AR 400-700nm
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 lens's thickness at the edge is 3 mm, and it thickens towards the center to also 3 mm. The effective focal length (EFL) of this lens is 4000 mm.
The lens is made of BK7 Schott, a popular optical glass due to its excellent optical properties and relatively low cost. The curvature of the lens is defined by a radius of 2074.9 mm on the convex side, while the plano side has no curvature.
This lens is coated with EKS 3217-i0 on both the front and back surfaces. This anti-reflection coating is designed to reduce reflection losses at wavelengths between 400 and 700 nm. The coating ensures high transmission and low reflection, making it suitable for various applications, including imaging systems, beam shaping, and laser applications within the specified wavelength range.
