This is a Plano-Convex lens from CeNing Optics, a renowned vendor in the optical industry. The lens has a base shape of a circle and is designed for use in spherical applications. It is made from N-BK7, a popular glass type known for its excellent optical properties, particularly its high refractive index and low dispersion. This specific lens has a diameter of 12.7 mm and a thickness at the edge of 1.8 mm, while the thickness at the center is 3.97 mm.
The effective focal length (EFL) of this lens is 20 mm, making it suitable for a wide range of applications that require moderate magnification. The lens's radius of curvature (R1) is 10.37 mm, and the back focal length (BFL) is 17.39 mm. The inner and outer radii are both 0, indicating a plano-convex design.
This lens is uncoated, meaning it does not have any additional layers to enhance its optical properties. While this may result in a lower transmission rate and a higher susceptibility to environmental factors, it also means the lens is more cost-effective and suitable for applications where such enhancements are not necessary.
The lens is designed to work with a wavelength of 546.1 nm, a common wavelength used in many optical applications. It is currently in stock and can be purchased directly from the vendor's website, with the link provided in the item data.
