This is a Plano-Convex Lens, type Lens, sourced from Standa, a reputable vendor in the optical industry. The lens is spherical in shape, with a base shape of a circle, and is designed for use in a wide range of optical applications.
The lens has a diameter of 50.8 mm and a thickness at the edge of 4 mm, while the thickness at the center is 5 mm. The effective focal length (EFL) of the lens is 600 mm, making it suitable for applications that require long focal lengths. The radius of curvature (R1) of the lens is 310.02 mm, and it does not have an inner or outer radius.
The lens is made of n-bk7 Schott, a high-quality optical glass known for its excellent optical properties. The lens is uncoated, meaning it does not have any anti-reflective or other coatings applied to its surface. This can make it more susceptible to reflections and other optical aberrations, but it also makes it more cost-effective and versatile.
The lens is designed to work with light of a wavelength of 546 nm, although it can be used with other wavelengths as well. It is in stock and ready for immediate use, as indicated by its valid weblink status.
