A240-B 9.94 mm Dia. D-LAK6 Molded Glass Aspheric Lenses; EFL=8 mm; NA=0.5 AR 650-1050nm

The A240-B is a high-quality aspheric lens, precision-molded from D-LAK6 glass, a type of glass known for its excellent optical properties. This lens boasts a diameter of 9.94 mm and a thickness of 1.15 mm at the edge, making it a compact yet powerful optical component. The effective focal length (EFL) of this lens is 8 mm, which is a versatile focal length for many optical applications.

The lens has a high numerical aperture (NA) of 0.5, which allows for a wide angle of acceptance and a high light-gathering capacity. This makes the A240-B ideal for applications that require high resolution and high contrast. The lens also features an aspheric surface on both sides, which helps to reduce spherical aberration and improve image quality.

The A240-B is coated with a broadband anti-reflection coating, specifically designed for the wavelength range of 650-1050 nm. This coating reduces surface reflections, thereby increasing the amount of light transmitted through the lens. This is particularly beneficial in applications such as laser systems, biomedical imaging, and machine vision, where high transmission and low loss are crucial.
