110-0405E 38.1 mm Dia. x 50 mm FL; Uncoated; Plano-Convex Lens

The 110-0405E is a Plano-Convex lens with a diameter of 38.1 mm and a focal length of 50 mm. This lens is sourced from EKSMA Optics, a reputable vendor known for their high-quality optical components. The lens is made of BK7 glass, a popular choice due to its excellent optical properties and versatility.

The lens's geometry is characterized by a thickness of 3.7 mm at the edge and 12 mm at the center. The radius of curvature (R1) is 25.9 mm, while the inner and outer radii are both 0 mm, indicating a plano surface on the opposite side of the convex surface. The effective focal length (EFL) is 50 mm.

This lens is uncoated, meaning it does not have any additional layers to enhance its optical properties. While coatings can be beneficial in reducing reflections, increasing transmission, and protecting the lens surface, an uncoated lens can be a suitable choice for applications where such enhancements are not required.

The item data provided does not specify a particular wavelength, but the lens's material (BK7) has a high transmission rate in the visible spectrum, making it suitable for a wide range of applications in this range.
