45-147 4.5mm Dia. x 9.0mm FL; Uncoated; Plano-Convex Lens
The 45-147 4.5mm Dia. x 9.0mm FL is a high-quality plano-convex lens sourced from Edmund Optics. This lens, with a base shape of a circle, is designed for use in a variety of optical applications.
The lens has a diameter of 4.5mm and a thickness at the edge of 1.8mm, transitioning to a thickness at the center of 2.38mm. The effective focal length (EFL) of this lens is 9mm, making it suitable for systems that require a longer focal length. The radius of curvature (R1) is 4.65mm, and the back focal length (BFL) is 7.41mm, providing a clear understanding of the lens's curvature and optical properties.
The lens is made from n-BK7 Schott, a popular optical glass known for its excellent optical properties and versatility. The lens is uncoated, which means it does not have any anti-reflective or other coatings applied to it. This can be beneficial in certain applications where the user does not require the additional properties provided by coatings.
The wavelength for this lens is 587.6nm, which is in the visible light spectrum. This makes it suitable for use in applications that involve visible light.
