84-291 15mm Dia. x 75mm FL UV-AR Coated; UV Plano-Convex Lens UV-AR 250-425nm

The 84-291 is a UV Plano-Convex Lens, 15mm in diameter and with a focal length of 75mm, offered by Edmund Optics. This lens is designed for use within the ultraviolet spectrum, specifically between 250 and 425nm, making it ideal for applications such as UV curing, analytical instrumentation, and UV imaging.

The lens is made from fused silica, a material known for its high transmittance in the UV range and excellent thermal shock resistance. The front and back surfaces of the lens are coated with the EDM UV STD CURVE anti-reflection coating, which enhances its performance by reducing surface reflections and increasing transmission.

The lens geometry includes a center thickness of 3mm and an edge thickness of 2.17mm, providing a balance between weight and optical performance. The inner and outer radii are 0mm, indicating a flat surface on the non-curved side of the lens. The lens's base shape is circular, and its shape is spherical, which is common in plano-convex lenses and contributes to its wide field of view.

The lens's design and construction make it suitable for use in various applications, including UV microscopy, spectroscopy, and other UV-based optical systems. Its high-quality materials, precise construction, and UV-optimized design make it a reliable choice for users seeking a high-performance UV lens.
