32-477 25.0mm Dia. x 50.0mm FL Uncoated; Plano-Convex Lens
The 32-477 is a 25.0mm diameter, 50.0mm focal length Plano-Convex lens, sourced from the renowned optical component vendor, Edmund Optics. This lens, designed for general-purpose use, is a Spherical Lens with a Base Shape of Circular and a Sub Type of Plano-Convex.
The lens's geometry is defined by a 25.0mm diameter, a 1.68mm edge thickness, and a 4.9mm center thickness. The Effective Focal Length (EFL) is 50.0mm, and the Radius of Curvature (R1) is 25.84mm. The Back Focal Length (BFL) is 46.75mm, and both the Inner and Outer Radius are 0mm, indicating a plano surface.
The lens is made of N-BK7 Schott, a popular optical glass due to its excellent optical properties, including a high Abbe number and low dispersion. The lens is uncoated, which means it does not have any anti-reflective or other coatings. This may result in higher reflective losses and a lower transmission rate compared to coated lenses. However, uncoated lenses are often more cost-effective and suitable for applications where coating is not required or desirable.
The lens's design wavelength is 587.6nm, which is the wavelength of light at which the lens is optimized for use. This wavelength falls within the visible light spectrum, making this lens suitable for applications involving visible light.
