A240-C 9.94 mm Dia. D-LAK6 Molded Glass Aspheric Lenses; EFL=8 mm; NA=0.5 AR 1050-1620nm

The A240-C is a high-quality aspheric lens, precision-molded from D-LAK6 glass, a material renowned for its excellent optical properties. This lens boasts a diameter of 9.94 mm and an effective focal length (EFL) of 8 mm, making it suitable for a wide range of applications. The lens features a high numerical aperture (NA) of 0.5, enhancing its light-gathering capabilities and improving image quality.

The lens's aspheric design is a significant advantage, as it reduces spherical aberration, a common issue in traditional spherical lenses. This results in improved image sharpness and clarity, especially at the lens's edges. The lens's geometry includes a center thickness of 3.69 mm and an edge thickness of 1.15 mm, contributing to its robustness and durability.

The A240-C is coated with a broadband anti-reflective (AR) coating, optimized for the 1050-1620 nm wavelength range. This coating reduces surface reflections, improving light transmission and enhancing the lens's performance in infrared applications. The lens's coating is durable and resistant to environmental factors, ensuring long-lasting performance.

This lens is available from Thorlabs, a leading vendor in the optical components industry.
