The MNN203 is a 25.4 mm diameter Negative Meniscus Lens, sourced from the reputable vendor WTS Photonics. This lens is a Spherical Lens with a Sub Type of Concave-Convex, designed for use in optical systems that require a negative meniscus lens. The lens's base shape is circular, ensuring consistent performance across its entire surface.
The geometry of the MNN203 is meticulously crafted, with a thickness edge of 3.82 mm and a thickness center of 3 mm. The effective focal length (EFL) is -200 mm, indicating its negative meniscus nature. The first radius of curvature (r1) is 89.95 mm, while the second radius (r2) is 47.64 mm. The back focal length (bfl) is -197.82 mm, and both the inner and outer radii are 0 mm, indicating a flat surface.
The lens is made from N-BK7 Schott, a high-quality optical glass known for its excellent optical properties. The wavelength for which this lens is designed is 588 nm. The lens is uncoated, offering a cost-effective solution for applications where coating is not a necessity.
