MNP205 25.4 mm Dia. N-BK7 Positive Meniscus Lens; EFL=300mm Uncoated
The MNP205 is a 25.4 mm diameter Positive Meniscus Lens, featuring a convex-concave shape, sourced from WTS Photonics. This lens is designed for use in systems with a focal length of 300mm and is uncoated.
The lens is made from N-BK7 Schott, a popular material in the optical industry due to its excellent optical properties. The geometry of the lens includes a thickness of 2.98mm at the edge and 3.5mm at the center, with an effective focal length (EFL) of 300mm. The radii of curvature are 94.19mm for the first surface and 235.5mm for the second surface, resulting in a back focal length (BFL) of 296.27mm.
The lens is circular in shape, making it suitable for a wide range of applications. The uncoated design offers simplicity and cost-effectiveness, although it may have lower damage threshold compared to coated versions. The lens is currently in stock and can be purchased directly from the vendor's website.
