AL1512-C 15 mm Dia. S-LAH64 High-Precision; CNC Polished Aspheric Lenses; EFL=12 mm; NA=0.55 AR 1050-1700nm
The AL1512-C is a high-precision aspheric lens, meticulously crafted by Thorlabs. This lens boasts a 15 mm diameter and is constructed from S-LAH64, a material renowned for its optical qualities. The lens is designed for use with a wavelength of 780 nm, making it suitable for a wide range of applications.
The lens features an effective focal length (EFL) of 12 mm, which is a crucial parameter in lens selection. The EFL determines the lens's magnification power and is inversely proportional to the angle at which the lens captures or focuses light. A shorter EFL, like that of the AL1512-C, results in a wider field of view and a larger image.
The AL1512-C's high numerical aperture (NA) of 0.55 further enhances its light-gathering capabilities. The NA is a dimensionless quantity that measures the light-gathering ability of an optical system. A higher NA allows for the capture of more light, which can lead to improved image quality and resolution.
The lens is CNC polished, ensuring superior surface quality and accuracy. It is coated with a broadband anti-reflective (AR) coating, optimized for the 1050-1700 nm range. This coating reduces surface reflections, thereby increasing the amount of light transmitted through the lens.
