45-159 12mm Dia. x 48mm FL Uncoated; Double-Convex Lens
The 45-159 is a 12mm diameter, double-convex lens with a focal length of 48mm, sourced from Edmund Optics. This lens is uncoated, which means it does not have any additional layers to protect the surface or enhance its optical properties.
The lens's base shape is circular, and it features a spherical geometry. The thickness at the edge of the lens is 2mm, while the thickness at the center is 2.74mm. The effective focal length (EFL) is 48mm, and the radius of curvature for the first surface (R1) is 49.14mm, while the second surface (R2) has a radius of curvature of -49.14mm. The back focal length (BFL) of this lens is 47.09mm.
The lens is made of n-BK7 Schott, a popular optical glass known for its excellent optical properties and versatility. The lens is designed to work at a wavelength of 587.6nm.
Please note that the lens does not have any coating, which means it may be more susceptible to environmental factors and may not perform as well in certain applications as coated lenses. However, uncoated lenses can be advantageous in certain situations, such as when minimal reflection is required.
