89-412 5mm Dia. x 15mm FL Uncoated; UV Plano-Convex Lens
The 89-412 is a 5mm diameter, 15mm focal length uncoated plano-convex lens, specifically designed for UV applications. Sourced from the reputable optical vendor, Edmund Optics, this lens is a reliable choice for various optical systems.
The lens's geometry is characterized by a 5mm diameter, 1.23mm edge thickness, and 1.7mm center thickness. The effective focal length (EFL) is 15mm, and the radius of curvature (R1) is 6.88mm. The back focal length (BFL) is 13.83mm, and both the inner and outer radii are 0mm, indicating a plano surface on one side and a curved surface on the other.
The lens is made of fused silica (mal-1965), a material known for its excellent transparency in the ultraviolet region. The wavelength for this lens is 587.6nm. The lens's shape is spherical, and it is uncoated, which means it does not have any anti-reflective or other coatings.
