SLB-50-150N 50.0 mm Dia. x -150.0 mm FL; Plano-Concave Lens Uncoated
The SLB-50-150N is a Plano-Concave Lens with a 50.0 mm diameter and a focal length of -150.0 mm, sourced from OptoSigma. This lens is made of n-BK7 Schott, a high-quality borosilicate glass known for its excellent optical properties, making it suitable for various applications.
The lens features a concave shape with an inner radius of 0 mm and an outer radius of 0 mm. The center thickness is 3 mm, while the edge thickness is 7.1 mm, providing a robust structure. The back focal length (BFL) is -152 mm, slightly longer than the specified focal length, which is common in Plano-Concave lenses.
This lens is uncoated, meaning it does not have any additional layers to enhance its optical properties. While this may result in a lower transmission rate and increased susceptibility to environmental factors, it also means the lens has a broader spectral range and can be used with various wavelengths, including the specified 546.1 nm.
The SLB-50-150N is currently in stock and available for immediate purchase through the provided web link. Its versatility and high-quality construction make it a valuable addition to any optical system.
