The 41570 is a Plano-Convex Lens, a type of spherical lens, sourced from the reputable vendor MKS/Newport. This lens is characterized by its circular base shape and uncoated surface, making it a versatile choice for various optical applications.
The lens has a diameter of 38.1 mm and a thickness at the edge of 2.3 mm, while the center thickness measures 5 mm. The effective focal length (EFL) is 150 mm, indicating the lens's ability to focus light to a point 150 mm away from the lens's curved surface.
The radius of curvature (R1) of the lens is 68.7 mm, and the back focal length (BFL) is 146.5 mm. The inner radius is 0, suggesting a simple, straightforward design.
The lens is made from UVFS Mal-1965 material, optimized for use with a wavelength of 589 nm. This material choice contributes to the lens's high-quality performance in its designated applications.
