G312006331 4 mm Dia. N-BK7 Plano-Convex Lens; EFL=4mm

The G312006331 is a Plano-Convex lens with a 4 mm diameter, sourced from Qioptiq Photonics. This lens is designed for use in optical systems that require a 4mm effective focal length (EFL). The lens is made of N-BK7 glass, a popular material in the optical industry due to its excellent optical properties and versatility.

The lens geometry includes a thickness of 0.45mm at the edge and 2mm at the center. The front surface of the lens has a radius of curvature of 2.07mm, while the back surface is flat. The lens does not have any inner or outer radius, indicating a uniform thickness across the lens.

The lens is coated with Qio AL RALVIS AOI 45 on both the front and back surfaces. This coating is designed to enhance the lens's performance in specific wavelengths, in this case, 588nm.

The lens is spherical in shape, a common choice for its simplicity and wide range of applications. The Plano-Convex design is also a popular choice due to its ability to focus light without introducing significant aberrations.
