AL50100M-C 50 mm Dia. N-BK7 High-Precision; CNC Polished Aspheric Lenses; EFL=100 mm; NA=0.24 AR 1050-1700nm
The AL50100M-C is a high-precision aspheric lens offered by Thorlabs, boasting a 50 mm diameter and a focal length of 100 mm. This lens is crafted from N-BK7, a popular borosilicate glass known for its excellent optical properties, making it an ideal choice for various applications.
The lens's aspheric design is achieved through CNC polishing, a process that ensures high surface accuracy and low scatter. This design significantly reduces spherical aberration, a common issue in traditional spherical lenses, thereby improving image quality and resolution.
The lens features a numerical aperture (NA) of 0.24, which determines the light-gathering capability of the lens. A higher NA allows for greater light collection, making this lens suitable for applications requiring high light transmission.
The lens is coated with a broadband anti-reflective coating, optimized for the 1050-1700 nm range. This coating reduces surface reflections, enhancing transmission and minimizing losses. It also provides protection against environmental factors, ensuring longevity and reliability.
