89-434 25mm Dia. N-BK7 Hyperbolic Aspheric Lens; EFL=100mm; NA=0.13 Laser V-Coat 532nm

This is a high-quality 25mm diameter N-BK7 Hyperbolic Aspheric Lens, designed with an effective focal length (EFL) of 100mm and a numerical aperture (NA) of 0.13. The lens is sourced from the renowned optical vendor, Edmund Optics, and is available for immediate use, as indicated by its valid in-stock weblink status.

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 various applications, particularly where high image quality and low chromatic aberration are crucial.

The lens features a hyperbolic aspheric shape, which is a type of aspheric lens with a hyperbolic profile. This design offers superior optical performance compared to traditional spherical lenses, reducing spherical aberration and providing a wider field of view. The lens has a thickness of 2.57mm at the edge and 4.05mm at the center, ensuring robustness and durability.

The lens is coated with Edmund Optics' Laser V-Coat 532nm, a broadband anti-reflection coating specifically designed for 532nm wavelengths. This coating significantly reduces surface reflections, improving transmission and enhancing the overall performance of the lens.
