355392-C 4 mm Dia. D-ZLAF52LA Molded Glass Aspheric Lenses; EFL=2.8 mm; NA=0.6 AR 1050-1700nm

The 355392-C is a high-quality aspheric lens from Thorlabs, designed with a 4 mm diameter and a molded glass construction using D-ZLAF52LA CGDM material. This lens is specifically engineered for use in the 1050-1700nm wavelength range, making it suitable for a variety of applications in the infrared spectrum.

The lens boasts an effective focal length (EFL) of 2.8 mm, providing a compact and efficient optical solution. It also features a high numerical aperture (NA) of 0.6, allowing for a wide angle of acceptance and increased light gathering capability. The aspheric design of the lens helps to reduce spherical aberration, providing superior image quality.

The 355392-C is coated with a broadband anti-reflection (AR) coating on both the front and back surfaces, which significantly reduces surface reflections and increases transmission in the specified wavelength range. This coating enhances the overall performance of the lens, making it an ideal choice for demanding optical applications.

The lens has a center thickness of 2.24 mm and edge thickness of 1.339 mm, providing excellent mechanical stability. The lens is currently in stock and available for immediate shipping, as indicated by its valid weblink status.
