MNN207 25.4 mm Dia. N-BK7 Negative Meniscus Lens; EFL=-500mm Uncoated
The MNN207 is a 25.4 mm diameter Negative Meniscus Lens, featuring a concave-convex base shape and a circular geometry. This lens is sourced from WTS Photonics, a reputable vendor in the optical industry. The lens's design includes a 3.82 mm thickness at the edge, tapering down to a 3.5 mm thickness at the center, providing a robust structure while minimizing unnecessary weight.
The lens's effective focal length (EFL) is -500mm, indicating its diverging nature. This property is further emphasized by the back focal length (BFL) of -496.94mm. The radii of curvature for the first and second surfaces are 235.5mm and 122.74mm, respectively, contributing to the lens's overall optical performance.
The lens is crafted from N-BK7 Schott, a popular material in the optical industry due to its excellent optical properties and versatility. The lens is designed to operate at a wavelength of 588nm. Notably, the lens is uncoated, offering users the flexibility to apply their preferred coating based on their specific application requirements.
