32-022 3mm Dia. x 4.5mm FL; Uncoated; Double-Convex Lens
The 32-022 is a 3mm diameter, double-convex lens with a focal length of 4.5mm, sourced from the renowned optical vendor, Edmund Optics. This lens, with its spherical shape, is designed for use in a wide range of optical applications, thanks to its uncoated surface that allows for maximum light transmission.
The lens's geometry is meticulously designed, with an edge thickness of 1.47mm and a center thickness of 2mm. The double-convex design, characterized by its first radius (R1) of 4.29mm and second radius (R2) of -4.29mm, ensures a high level of optical performance. The back focal length (BFL) of the lens is 3.78mm, making it suitable for applications where a short back focal length is required.
The lens is made from the high-quality material N-BK7 Schott, a borosilicate glass known for its excellent optical properties, including low dispersion and high transmission in the visible spectrum. The wavelength for this lens is 587.6nm, which falls within the visible light spectrum.
Please note that the lens does not come with any coating, which means it may be more susceptible to environmental factors such as dust and moisture. However, this also means that it can offer maximum light transmission, making it ideal for applications where high light transmission is a priority.
