This is a high-quality double-convex lens, designed for use with lasers at a wavelength of 1064nm. The lens is sourced from the reputable vendor MKS/Newport, and is available directly from their website. The lens is made from the material n-BK7 schott, a popular choice for its excellent optical properties.
The lens has a diameter of 25.4mm and a thickness at the edge of 3mm. The center thickness is 6.226mm, providing a robust structure for your optical setup. The effective focal length (EFL) of the lens is 50.2mm, making it suitable for a variety of applications.
The lens features a double-convex geometry, with radii of curvature of 50.806mm for the first surface and -50.806mm for the second. This geometry provides a high degree of focusing power, making it ideal for use in laser systems. The back focal length (BFL) is 48.1mm, which should be taken into account when designing your optical setup.
The lens is coated with a new AR-33 coating on both the front and back surfaces. This coating is specifically designed for use with lasers at a wavelength of 1064nm, providing excellent transmission and reducing unwanted reflections.
