110-0205E 25.4 mm Dia. x 30 mm FL; Uncoated; Plano-Convex Lens

The 110-0205E is a Plano-Convex lens with a diameter of 25.4 mm and a focal length of 30 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 material in the optical industry due to its excellent optical properties and durability.

The lens geometry is characterized by its edge thickness of 1.9 mm and center thickness of 8.5 mm. The inner and outer radii are both zero, indicating a plano-convex shape. The effective focal length (EFL) is 30 mm, which is the distance from the lens's principal point to the focal point. The lens's shape is spherical, which is a common shape for optical lenses due to its ease of manufacturing and good optical performance.

This lens is uncoated, meaning it does not have any anti-reflective or other coatings. While coatings can enhance the performance of a lens by reducing reflections, increasing transmission, or providing other benefits, uncoated lenses can be suitable for certain applications where such enhancements are not necessary.

The lens is designed to work at a wavelength of 546 nm. This wavelength falls within the visible light spectrum, making this lens suitable for applications involving visible light.
