84-282 30mm Dia. x 50mm FL Uncoated; UV Plano-Convex Lens

The 84-282 is a 30mm diameter, 50mm focal length uncoated plano-convex lens, specifically designed for UV applications. This lens, sourced from Edmund Optics, is a spherical lens with a base shape of a circle, ensuring a wide field of view and minimal distortion.

The lens geometry is meticulously designed, with a thickness of 1.41mm at the edge and 7mm at the center, providing a balanced structure for various applications. The effective focal length (EFL) is 50mm, making it suitable for medium-range focus requirements. The radius of curvature (R1) is 22.92mm, and the back focal length (BFL) is 45.2mm, contributing to the lens's overall optical performance.

The lens is made from fused silica, a material with the material ID of mal-1965. This material is known for its excellent transparency in the UV region, making this lens an ideal choice for UV applications. The lens is uncoated, which means it does not have any additional layers to enhance light transmission or protect the lens surface. However, this does not affect its performance in UV applications, where coating might not be necessary.

The wavelength of this lens is 587.6nm, which is in the visible light spectrum. However, due to its UV-optimized design and material, it is most suitable for UV applications.
