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 is 3 mm, and it maintains the same thickness at the center. The effective focal length (EFL) of this lens is an impressive 5000 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 2593.6 mm, while the second surface has no curvature, hence the term 'Plano'.
This lens is coated with EKS 3217-i0 on both the front and back surfaces. This coating is designed to provide anti-reflective properties within the wavelength range of 400-700 nm. This makes the lens ideal for applications that require high transmission and low reflection, such as imaging systems, beam shaping, and laser applications.
The lens is currently in stock and available for immediate purchase. For more information, please refer to the vendor's website provided in the weblinks section.
