This is a Plano-Convex Lens, type of spherical lens, offered by Standa, a renowned vendor in the optical industry. The lens has a base shape of a circle and is designed for use in the visible light spectrum, specifically at a wavelength of 546 nm.
The lens has a diameter of 25.4 mm and a thickness at the edge of 2.9 mm. The center thickness of the lens is 3 mm, providing a balanced structure for light transmission. The effective focal length (EFL) of the lens is 1500 mm, making it suitable for applications requiring long-distance focusing.
The lens's curvature is defined by a radius of 775.05 mm on the convex side. The inner and outer radii are 0 mm, indicating a uniform curvature across the lens surface.
The lens is made of n-BK7 Schott, a high-quality optical glass known for its excellent transparency and low dispersion. This material makes the lens suitable for a wide range of optical applications.
Notably, this lens is uncoated. Coatings are often applied to lenses to enhance their performance by reducing reflections, increasing transmission, or providing other benefits. However, this lens, in its uncoated form, offers a bare, unaltered lens surface, which may be desirable for certain applications.
