357775-B 6.325 mm Dia. D-LAK6 Molded Glass Aspheric Lenses; EFL=4 mm; NA=0.6 AR 600-1050nm

The 357775-B is a high-quality aspheric lens, precision-molded from D-LAK6 glass, a unique material known for its excellent optical properties. This lens boasts a diameter of 6.325 mm and a center thickness of 2.898 mm, providing a robust and compact design ideal for various applications.

The lens features an effective focal length (EFL) of 4 mm, which is the distance from the lens's center to the focal point when the lens is imaging an object at infinity. This EFL makes the lens suitable for systems requiring a wide field of view and high image quality.

The lens's design includes a high numerical aperture (NA) of 0.6, which is the sine of the maximum angle at which the lens can accept or emit light rays. A high NA allows for greater light-gathering capability and improved resolution, making this lens ideal for applications requiring high-resolution imaging.

The 357775-B lens comes with broadband anti-reflection (AR) coatings, specifically designed for the 600-1050nm wavelength range. These coatings reduce surface reflections, increasing the lens's transmission and improving overall system performance.
