LB01-25-75 25.4 mm Dia. N-BK7 Double-Convex Lens; EFL=75mm Uncoated
This is the LB01-25-75, a 25.4 mm diameter Double-Convex lens with a focal length of 75mm, sourced from CeNing Optics. The lens is made of N-BK7, a popular glass type known for its excellent optical properties, particularly its low dispersion.
The lens features a base shape of a circle, with an edge thickness of 2mm and a center thickness of 4.11mm. The inner and outer radii are both zero, indicating a symmetrical design. The radii of curvature for the first and second surfaces are 77.09mm and -77.09mm respectively, suggesting a strong converging lens.
The lens is uncoated, meaning it does not have any anti-reflective coatings. This could lead to some reflection loss, but it also means the lens is simpler and more cost-effective. The wavelength for this lens is 546.1nm, which is in the green part of the spectrum.
This lens is suitable for a wide range of applications, including imaging systems, beam shaping, and laser applications. It's important to note that the lack of coating may affect its performance in high-power laser applications, but it's otherwise a versatile and high-quality lens.
