This HO-PXL25-3.2C optical lens, sourced from Holmarc Opto-Mechatronics, is a Plano-Convex Spherical Lens with a diameter of 25mm and a thickness at the edge of 2mm. The Effective Focal Length (EFL) of this lens is 80mm, making it suitable for a variety of optical applications.
The lens is made of N-BK7, a popular optical glass from Schott, which is known for its excellent optical properties and wide transparency range. The lens has a single layer of MgF2 coating on both the front and back surfaces, which is designed to reduce reflection and increase transmission.
The curvature of the lens is defined by a radius of 41.729 on the curved side, while the other side is flat. The lens does not have any inner or outer radius, indicating a uniform thickness.
