89-440 25mm Dia. N-BK7 Hyperbolic Aspheric Lens; EFL=50mm; NA=0.25 Laser V-Coat 1064nm
This is a high-quality aspheric lens from Edmund Optics, catalog number 89-440. It is designed for use with a wavelength of 1064nm and features a laser V-coat for optimal performance. The lens has a diameter of 25mm and an effective focal length (EFL) of 50mm, making it suitable for a variety of applications.
The lens is made from N-BK7 Schott glass, a popular material due to its excellent optical properties and wide transmission range. The aspheric design of the lens helps to reduce spherical aberration, improving the quality of the image. The lens has a numerical aperture (NA) of 0.25, which determines the light-gathering ability of the lens.
The lens features a best form aspheric surface, which is the most common type of aspheric surface. It has a thickness of 1.42mm at the edge and 4.3mm at the center. The front and back surfaces of the lens are coated with Edmund Optics' laser V-coat, which is designed for use with 1064nm lasers.
This lens is available for purchase from the Edmund Optics website, where you can find more detailed specifications and pricing information. The website also provides information on shipping and handling, as well as return and refund policies.
