This is a Plano-Convex lens, type of spherical lens, sourced from Qioptiq Photonics. It features a circular base shape with a diameter of 3 mm and a thickness edge of 0.34 mm. The thickness at the center of the lens is 1.5 mm, and the effective focal length (EFL) is 3 mm, designed for use within the wavelength range of 450-700 nm.
The lens is made of N-BK7, a popular glass type in the optical industry, known for its excellent optical properties. The inner radius of the lens is 0, and the outer radius is also 0, indicating a plano-convex geometry.
The lens is coated with qio bbar arb2visnbk7 on both the front and back surfaces. This coating enhances the lens's performance within the specified wavelength range.
Please note that the lens's shape is spherical, which means it has a curvature that is part of a sphere. This curvature can cause spherical aberration, a common optical problem, but it is also what makes this lens a Plano-Convex lens.
