355230-A 6.325 mm Dia. D-ZLAF52LA Molded Glass Aspheric Lenses; EFL=4.5 mm; NA=0.55 AR 350-700nm

The 355230-A is a high-quality aspheric lens from Thorlabs, designed with a 6.325 mm diameter and a molded glass construction using D-ZLAF52LA CGDM material. This lens is specifically engineered for use in the 780 nm wavelength range.

The lens boasts an effective focal length (EFL) of 4.5 mm, providing a compact and efficient optical solution. The aspheric design, characterized by its non-spherical surface, helps to minimize spherical aberration, resulting in improved image quality and resolution.

The lens has a numerical aperture (NA) of 0.55, which determines the light-gathering capability and angular field of view. This NA, combined with the lens's EFL, allows for a wide field of view and high light-gathering capacity.

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 improving overall system performance.

The 355230-A is currently in stock and available for immediate purchase through the Thorlabs website. With its advanced design and high-performance characteristics, this lens is an excellent choice for a wide range of optical applications.
