MNP202 25.4 mm Dia. N-BK7 Positive Meniscus Lens; EFL=150mm Uncoated
The MNP202 is a 25.4 mm diameter Positive Meniscus Lens, sourced from the reputable vendor WTS Photonics. This lens is designed with a unique convex-concave spherical shape, providing a base shape of a circle. The lens's geometry is meticulously crafted, with an edge thickness of 2.95 mm and a center thickness of 4 mm. The effective focal length (EFL) of this lens is 150mm, making it suitable for a wide range of optical applications.
The lens's first radius of curvature (R1) is 42.36 mm, while the second radius (R2) is 89.95 mm. The back focal length (BFL) is 145.2 mm, and both the inner and outer radii are 0 mm. The lens is made from N-BK7 Schott, a high-quality optical glass known for its excellent optical properties and durability.
The lens is designed to operate at a wavelength of 588 nm. It features a spherical shape and comes uncoated, offering users the flexibility to apply their preferred coating based on their specific application requirements.
