110-0207E 25.4 mm Dia. x 40 mm FL; Uncoated; Plano-Convex Lens

The 110-0207E is a Plano-Convex lens with a diameter of 25.4 mm and a focal length of 40 mm. This lens is sourced from EKSMA Optics, a reputable vendor known for their high-quality optical components. The lens is made of BK7 Schott, a popular glass type in the optical industry due to its excellent optical properties and versatility.

The lens geometry is characterized by its edge thickness of 1.8 mm and center thickness of 6.1 mm. The inner and outer radii are 0 mm, indicating a plano surface on one side and a curved surface on the other. The effective focal length (EFL) is 40 mm, which is the distance from the lens's principal point to the focal point when the lens is focused at infinity.

This lens is uncoated, meaning it does not have any anti-reflective or other coatings applied to its surfaces. While coatings can enhance the performance of a lens by reducing reflections, increasing transmission, or providing other benefits, uncoated lenses can be a cost-effective solution for many applications.

The wavelength of 546 nm suggests that this lens is designed for use in the visible light spectrum. It is important to note that the performance of a lens can vary depending on the wavelength of light it is intended to transmit.
