AL1225M-A 12.5 mm Dia. N-BK7 High-Precision; CNC Polished Aspheric Lenses; EFL=25 mm; NA=0.23 AR 350-700nm
The AL1225M-A is a high-precision asperic lens offered by Thorlabs, a leading global manufacturer of photonics equipment. This lens boasts a 12.5 mm diameter and is crafted from N-BK7, a popular glass type known for its excellent optical properties.
The lens's asphere design, combined with CNC polishing, ensures high-quality imaging and minimal spherical aberration. The effective focal length (EFL) is 25 mm, making it suitable for a wide range of optical applications.
The lens's numerical aperture (NA) is 0.23, indicating a wide acceptance angle and high light-gathering capability. It features anti-reflection (AR) coatings on both surfaces, optimized for the 350-700 nm wavelength range, which reduces surface reflections and improves transmission.
This lens is available for immediate purchase and is currently in stock, according to the vendor's website. For more information, including technical drawings and specifications, please refer to the provided weblink.
