MNP206 25.4 mm Dia. N-BK7 Positive Meniscus Lens; EFL=400mm Uncoated

The MNP206 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 a variety of optical applications, with a focal length of 400mm and a base shape of a circle.

The lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties, including a high Abbe number and low dispersion. This makes it an ideal choice for applications that require high image quality and precise light control.

The geometry of the lens includes a thickness at the edge of 3.11mm and a center thickness of 3.5mm. The inner and outer radii are not specified, indicating a symmetrical design. The back focal length (BFL) is 396.06mm, and the effective focal length (EFL) is 400mm.

The lens is uncoated, which means it does not have any additional layers to enhance its optical properties. This may be suitable for applications where cost is a concern, or where specific coating requirements are not needed. However, it's important to note that uncoated lenses can be more susceptible to environmental factors such as dust and moisture, and may not perform as well in high-intensity light conditions.
