MNP207 25.4 mm Dia. N-BK7 Positive Meniscus Lens; EFL=500mm Uncoated

The MNP207 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 operating at a wavelength of 588 nm. The lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and wide transparency range.

The lens has an effective focal length (EFL) of 500mm, making it suitable for applications that require moderate to high magnification. The inner radius of the lens is 0, while the outer radius is also 0, indicating a symmetrical design. The center thickness of the lens is 3.5 mm, and the edge thickness is 3.19 mm, providing a robust structure.

The positive meniscus shape of the lens, with radii of curvature R1 at 124.17 mm and R2 at 235.5 mm, ensures a well-corrected image over a wide field of view. The back focal length (BFL) of the lens is 496.16 mm.

Notably, this lens is uncoated, which may affect its performance in high-light applications due to reflection losses. However, uncoated lenses are often preferred in applications where cost, ease of cleaning, or specific spectral requirements are important.
