AL4532-A 45 mm Dia. S-LAH64 High-Precision; CNC Polished Aspheric Lenses; EFL=32 mm; NA=0.61 AR 350-700nm
The AL4532-A is a high-precision aspheric lens, meticulously crafted by Thorlabs. This lens boasts a 45 mm diameter and is constructed from S-LAH64, a high-quality material from Ohara. The lens is designed for use with a wavelength of 780 nm, making it suitable for a wide range of optical applications.
The lens features an effective focal length (EFL) of 32 mm, which is the distance from the lens's optical center to the point at which it focuses light. This EFL, combined with the lens's high numerical aperture (NA) of 0.61, allows for a wide field of view and high light-gathering capability.
The AL4532-A's aspheric design is achieved through CNC polishing, resulting in superior surface accuracy and excellent optical performance. The lens's front and back surfaces are coated with a broadband anti-reflective coating (AR 350-700nm), which reduces surface reflections and increases transmission, thereby enhancing overall system performance.
This lens is available for purchase directly from Thorlabs, and the provided weblink indicates that it is currently in stock. With its high-precision design, broadband coating, and impressive optical specifications, the AL4532-A is an excellent choice for a wide variety of optical applications.
