SLB-50-170P 50.0 mm Dia. x 170.0 mm FL; Plano-Convex Lens Uncoated

The SLB-50-170P is a Plano-Convex lens with a diameter of 50.0 mm and a focal length of 170.0 mm. This lens is sourced from OptoSigma, a renowned vendor in the optical industry. The lens is made of n-BK7 Schott, a high-quality optical glass known for its excellent transparency and low auto-fluorescence.

The lens geometry is characterized by its spherical shape, with a center thickness of 6.6 mm and an edge thickness of 3 mm. The inner radius is 0 mm, and the outer radius is also 0 mm, indicating a plano surface on one side and a curved surface on the other. The effective focal length (EFL) is 170.0 mm, and the back focal length (BFL) is 165.6 mm. The radius of curvature (R1) is 88.23 mm.

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 preferred in applications where specific coatings may interfere with the desired optical properties.

The lens data is provided for a wavelength of 546.1 nm, which is a standard visible light wavelength. However, the lens's performance may vary for different wavelengths.
