MNP203 25.4 mm Dia. N-BK7 Positive Meniscus Lens; EFL=200mm Uncoated

The MNP203 is a 25.4 mm diameter Positive Meniscus Lens, featuring a convex-concave shape and sourced from WTS Photonics. This lens is designed for use in systems operating at a wavelength of 588 nm. The lens's primary features include an effective focal length (EFL) of 200mm, a large diameter of 25.4 mm, and a base shape of a circle.

The lens's geometry showcases a positive meniscus design, with a center thickness of 3.5 mm and an edge thickness of 2.72 mm. The radii of curvature for the first and second surfaces are 48.75 mm and 89.95 mm, respectively, resulting in a back focal length (BFL) of 194.51 mm. The inner and outer radii are both 0 mm, indicating a symmetrical lens profile.

The lens is crafted from N-BK7 glass, a popular material for optical components due to its excellent optical properties. This specific lens, however, is uncoated, meaning it does not have any additional anti-reflective or protective coatings applied to its surfaces.
