49-962 20mm Dia. x 50mm FL Uncoated; UV Plano-Convex Lens
The 49-962 is a 20mm diameter, 50mm focal length uncoated plano-convex lens, specifically designed for UV applications. Sourced from Edmund Optics, this lens is a part of their extensive catalog of optical elements, and is available for purchase directly from their website.
The lens is spherical in shape, with a base shape of circular. The geometry of the lens includes an inner radius of 0 and an outer radius of 0, indicating a uniform curvature. The thickness at the edge of the lens is 1.7mm, while the thickness at the center is 4mm. The effective focal length (EFL) of the lens is 50mm, and the back focal length (BFL) is 47.25mm. The radius of curvature (R1) is 22.92mm.
The lens is made from fused silica, as indicated by the Material ID [fused sil mal-1965]. This material is known for its excellent transmission properties in the UV range, making it ideal for UV applications. The lens is uncoated, which means it does not have any additional layers to enhance its optical properties or protect it from environmental factors.
The lens is designed to work with a wavelength of 587.6nm. It is important to note that the performance of the lens may vary depending on the specific wavelength and conditions of use. Therefore, it is recommended to consult the vendor or relevant technical documentation for more detailed information.
