A260-A 6.5 mm Dia. H-LAK54 Molded Glass Aspheric Lenses; EFL=15.29 mm; NA=0.16 AR 350-700nm

The A260-A is a high-quality aspheric lens from Thorlabs, designed with a 6.5 mm diameter and a molded H-LAK54 glass material. This lens is specifically engineered for use in the 780 nm wavelength range, making it suitable for various applications that require precise optical performance.

The lens features an effective focal length (EFL) of 15.29 mm, which is a critical parameter in determining the lens's magnification and field of view. The EFL, combined with the lens's high numerical aperture (NA) of 0.16, ensures excellent light-gathering capabilities and high-resolution imaging.

The A260-A's aspheric design significantly reduces spherical aberration, a common issue in traditional spherical lenses. This results in improved image quality, increased contrast, and sharper focus across the entire field of view.

The lens is coated with a broadband anti-reflective (AR) coating, optimized for the 350-700 nm range. This coating reduces surface reflections, enhancing transmission and minimizing ghosting and flare.

The A260-A is currently in stock, according to Thorlabs' website, and is available for immediate shipping. With its superior optical performance, robust construction, and reliable vendor, the A260-A is an excellent choice for a wide range of optical applications.
