AL100100 100 mm Dia. N-BK7 High-Precision; CNC Polished Aspheric Lenses; EFL=100 mm; NA=0.48 Uncoated

The AL100100 is a high-precision aspheric lens, measuring 100 mm in diameter, manufactured by Thorlabs. This lens is made from N-BK7, a popular glass type in the optical industry, known for its excellent optical properties and versatility. The lens is uncoated, which means it does not have any additional layers to enhance its optical properties.

The lens features a large effective focal length (EFL) of 100 mm, making it suitable for applications that require a long focal length. The numerical aperture (NA) is 0.48, indicating a wide acceptance angle for incoming light, which can be beneficial in various applications.

The lens's geometry is defined by its inner and outer radii, both of which are 0 in this case. The diameter is 100 mm, and the edge thickness is 8.4 mm. The center thickness is 36 mm. The lens's shape is aspheric, which means it has a non-spherical surface designed to reduce spherical aberration and improve optical performance.

The lens's aspheric surface is defined by several coefficients, including k1, k2, a2 front, a4 front, a6 front, a8 front, a10 front, and a12 front. These coefficients determine the precise shape of the lens surface, which is crucial for achieving the desired optical performance.
