45-024 20.0mm Dia. x -50 FL; Uncoated; Plano-Concave Lens

The 45-024 is a 20.0mm diameter Plano-Concave lens with a focal length of -50mm, sourced from the renowned optical component vendor, Edmund Optics. This lens, with its base shape being circular, is an uncoated spherical lens, designed to bend light rays inward towards a single focal point.

The lens has a thickness of 5.21mm at the edge and 3.5mm at the center, providing a sleek profile and efficient light manipulation. The back focal length (BFL) is measured at -52.31mm, and the effective focal length (EFL) is -50mm, both contributing to the lens's concave properties.

The lens material is n-BK7 Schott, a high-quality optical glass known for its excellent transparency and homogeneity. The lens is designed to work optimally with a wavelength of 587.6nm, making it suitable for a wide range of applications in the visible light spectrum.

Please note that this lens is uncoated, meaning it does not have any additional layers to enhance light transmission or protect the surface from environmental factors. However, this can be advantageous in certain applications where specific coatings may interfere with the desired optical outcomes.
