355392-B 4 mm Dia. D-ZLAF52LA Molded Glass Aspheric Lenses; EFL=2.8 mm; NA=0.6 AR 600-1050nm

The 355392-B is a high-quality aspheric lens, precision-molded from D-ZLAF52LA glass, a unique material with exceptional optical properties. This lens boasts a 4 mm diameter and a focal length of 2.8 mm, making it suitable for a wide range of applications where compactness and high performance are required.

The lens features a high numerical aperture (NA) of 0.6, which allows for a larger light-gathering capacity and improved resolution. The aspheric design further enhances the lens's performance by reducing spherical aberration, a common issue in traditional spherical lenses. This results in sharper images and more accurate light transmission.

The lens is coated with a broadband anti-reflective coating, specifically designed for the 600-1050nm wavelength range. This coating significantly reduces surface reflections, improving light transmission and reducing unwanted glare and ghosting.

The 355392-B is available from Thorlabs, a leading vendor in the optical components industry. According to the vendor's information, the lens is currently in stock, ensuring quick delivery and minimal lead times. The product's webpage provides further details and specifications, making it a valuable resource for those considering this lens for their optical systems.
