This is a Plano-Convex lens, a type of spherical lens, offered by Thorlabs with the product code LA1433-B. The lens is designed with a circular base shape and a diameter of 1 inch (25.4 mm). It has a thickness of 2 mm at the edge and 3.1 mm at the center. The effective focal length (EFL) of this lens is 150 mm, making it suitable for a variety of optical applications.
The lens is made of N-BK7, a popular glass type in the optical industry, manufactured by Schott. This material is known for its excellent optical properties, making it a common choice for various applications. The lens has an inner radius of 0 mm and an outer radius of 0 mm, indicating a plano-convex geometry.
