AL50100M-A 50 mm Dia. N-BK7 High-Precision; CNC Polished Aspheric Lens; EFL=100 mm; NA=0.24 AR 350-700nm
The AL50100M-A is a high-precision asperic lens offered by Thorlabs, a leading global manufacturer of photonics equipment. This lens boasts a 50 mm diameter and is crafted from N-BK7, a popular glass type known for its excellent optical properties. 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 100 mm and a numerical aperture (NA) of 0.24. The EFL is a measure of the lens's ability to focus light, while the NA indicates the range of angles over which the lens can accept or emit light. These specifications make the lens ideal for applications that require high-resolution imaging or precise light control.
The AL50100M-A is CNC polished, ensuring a smooth, uniform surface that enhances its optical performance. It also features anti-reflection (AR) coatings on both the front and back surfaces, which are designed to reduce light loss due to reflection. These coatings are effective over the 350-700 nm wavelength range, further broadening the lens's range of applications.
