08-084 18mm Dia. x 40mm FL; Uncoated; UV Double-Convex Lens
The 08-084 is a high-quality double-convex lens, boasting a diameter of 18mm and a focal length of 40mm. This lens is sourced from the reputable optical vendor, Edmund Optics, and is available for immediate purchase on their website.
The lens is constructed from fused silica, a material with the material ID 1965, ensuring durability and resistance to environmental factors. The base shape of the lens is circular, and it features a spherical geometry, with inner and outer radii of 0mm. The lens has a center thickness of 4.29mm and an edge thickness of 2mm, providing a robust structure.
The lens's geometry also includes a back focal length of 38.5mm and an effective focal length of 40mm. The curvature of the lens is defined by two radii, R1 and R2, which are 35.99mm and -35.99mm respectively. This curvature allows for a high level of light concentration, making this lens ideal for applications requiring intense light focus.
The lens is uncoated, meaning it does not have any additional layers to protect it from environmental factors or to enhance its optical properties. However, this does not affect its performance in UV applications, as indicated by its wavelength of 587.6nm.
