45-133 6mm Dia. x 30mm FL; Uncoated; Double-Convex Lens
The 45-133 is a 6mm diameter, 30mm focal length, uncoated, double-convex lens sourced from Edmund Optics. This lens is a spherical lens with a convex-convex base shape and a circular geometry, designed for use in a wide range of optical applications.
The lens has a diameter of 6mm, with a thickness of 2mm at the edge and 2.3mm at the center. The effective focal length (EFL) is 30mm, making it suitable for applications that require a moderate level of magnification. The first radius of curvature (R1) is 30.61mm, while the second radius of curvature (R2) is -30.61mm, indicating a strongly converging lens. The back focal length (BFL) is 29.23mm.
The lens is made from n-BK7 Schott, a high-quality optical glass known for its excellent transparency and low dispersion. This makes it suitable for use in applications that require high optical precision, such as imaging systems, beam shaping, and laser applications.
The lens is uncoated, meaning it does not have any anti-reflective or other surface coatings. This can result in higher levels of reflection at the lens surfaces, which may be a consideration for certain applications. However, the uncoated surface can also provide a higher level of durability and resistance to environmental conditions.
