A280-C 6.5 mm Dia. H-LAK54 Molded Glass Aspheric Lenses; EFL=18.4 mm; NA=0.15 AR 1050-1620nm

The A280-C is a high-quality aspheric lens, precision-molded from H-LAK54 glass, a type of optical crown glass known for its excellent homogeneity and transparency. This lens boasts a diameter of 6.5 mm and an effective focal length (EFL) of 18.4 mm, making it suitable for a wide range of optical applications.

The lens's design includes a high numerical aperture (NA) of 0.15, which enhances its light-gathering capability and resolution. The aspheric shape of the lens helps to minimize spherical aberration, a common issue in optical systems, thereby improving image quality and clarity.

The A280-C is coated with a broadband anti-reflection (AR) coating, specifically designed for the 1050-1620nm wavelength range. This coating reduces surface reflections, thereby increasing transmission and improving overall system performance.

The lens is available from Thorlabs, a leading global manufacturer of photonics equipment. According to the vendor's information, the lens is currently in stock, ensuring quick delivery times. The product's webpage provides further details and specifications, making it a valuable resource for those considering this lens for their optical systems.
