45-153 50.0mm Dia. x 250.0mm FL; Plano-Convex Lens Uncoated

The 45-153 is a Plano-Convex lens with a diameter of 50.0mm and a focal length of 250.0mm, sourced from the reputable optical vendor, Edmund Optics. This lens is uncoated, offering users a bare, unaltered optical surface for their specific applications.

The lens's geometry is characterized by a thickness of 2.5mm at the edge and 4.94mm at the center, providing a balanced distribution of material to ensure optimal light transmission and focus. The lens's effective focal length (EFL) is 250mm, making it suitable for applications requiring moderate to high magnification.

The lens's curvature is defined by a radius of 129.21mm on the curved face, contributing to the lens's overall focal length and light-bending capabilities. The back focal length (BFL) is 246.74mm, which is the distance from the lens's rear surface to the focal point. This information is crucial for designing optical systems that incorporate this lens.

The lens is made of N-BK7 Schott glass, a popular material in the optical industry due to its excellent optical properties and versatility. This lens is designed to work with a wavelength of 587.6nm, making it suitable for applications in the visible light spectrum.

Please note that the lens does not come with any coating. Coatings are often applied to lenses to enhance their performance by reducing reflections, increasing transmission, or providing other benefits. However, this lens is uncoated, offering a clean, unaltered optical surface for users who prefer to apply their coatings or do not require coatings for their specific applications.
