AL75150-C 75 mm Dia. S-LAH64 High-Precision; CNC Polished Aspheric Lenses; EFL=150 mm; NA=0.23 AR 1050-1700nm

The AL75150-C is a high-precision asperic lens offered by Thorlabs, a leading global manufacturer of photonics equipment. This lens boasts a diameter of 75 mm and a focal length of 150 mm, making it suitable for a wide range of applications.

The lens is crafted from n-BK7 Schott glass, a material known for its excellent optical properties and high damage threshold. The asphere is CNC polished, ensuring superior surface quality and low wavefront error. This results in high-resolution, high-contrast images, making the lens ideal for applications that require high optical performance.

The lens features a broadband anti-reflection coating, optimized for the 1050-1700 nm range. This coating reduces surface reflections, improving transmission and minimizing ghosting and flare. The coating is applied to both the front and back surfaces of the lens, ensuring optimal performance from all angles.

The lens has a numerical aperture (NA) of 0.23, which determines the light-gathering ability of the lens. A higher NA allows for the collection of more light, which can be beneficial in low-light conditions or when high resolution is required.

The lens is available for immediate purchase and is in stock on the Thorlabs website. With its high-quality construction, excellent optical performance, and broadband anti-reflection coating, the AL75150-C is an excellent choice for a wide range of optical applications.
