This is the G063042000 18 mm Dia. N-BK7 Mounted Plano-Convex Lens, a high-quality optical component sourced from Qioptiq Photonics. This lens, with its plano-convex design, is a spherical lens featuring a circular base shape and a single curvature.
The lens has a diameter of 18 mm and a thickness at the edge of 1.7 mm, while the center thickness measures 4.5 mm. The effective focal length (EFL) is 30 mm, making it suitable for a variety of optical applications. The lens is made of N-BK7, a popular glass type known for its excellent optical properties, particularly its high refractive index and low dispersion.
The lens is uncoated, meaning it does not have any additional layers to enhance its optical properties or protect it from environmental factors. However, this does not affect its performance in many applications where such coatings are not necessary.
The lens is mounted, which means it is ready for immediate use in optical systems. It is currently in stock and available for purchase through the provided web link.
