This is a G312341322 Plano-Convex Lens, a high-quality optical component sourced from Qioptiq Photonics. The lens has a diameter of 40 mm and a center thickness of 5 mm, with a 2.4 mm thickness at the edge. The effective focal length (EFL) of this lens is 150 mm, making it suitable for a variety of optical applications.
The lens is made from N-BK7, a popular glass type known for its excellent optical properties. This material is particularly suitable for use in the visible spectrum, with a wavelength of 588 nm. The lens is coated with qio bbar arb2visnbk7 on both the front and back surfaces, which enhances its performance in the visible light range.
The lens's geometry is spherical, with a radius of curvature (R1) of 78.3 mm on the convex side. The inner and outer radii are both 0, indicating a plano-convex design. This design is commonly used in optical systems due to its simplicity and versatility.
The lens is currently in stock and can be purchased directly from the Qioptiq Photonics website. For more information, please refer to the provided weblink.
