542-7205 25.4 mm Dia. x -50 mm FL; Uncoated; Plano-Concave Lens

The 542-7205 is a Plano-Concave Spherical Lens, sourced from EKSMA Optics, a leading vendor in the field of optical components. This lens boasts a diameter of 25.4 mm and a center thickness of 2.5 mm, making it a compact yet robust option for various applications.

The lens's focal length is -50 mm, indicating its concave nature. The inner radius is 0 mm, while the outer radius is also 0 mm, suggesting a uniform curvature throughout. The lens is designed to refract light rays inward, making it suitable for use in applications such as beam compression or diverging lenses.

The lens is crafted from Barium Fluoride (BaF2), a material with a wide transparency range, extending from the ultraviolet (UV) to the infrared (IR) spectrum, with a cutoff wavelength of 3000 nm. This broad transparency range makes the lens versatile, suitable for use in various optical systems.

Notably, the lens is uncoated. While coatings can enhance the performance of optical elements by reducing surface reflections, increasing transmission, or providing environmental protection, an uncoated lens can offer simplicity and cost-effectiveness in certain applications.
