The 37-801 is a Plano-Convex lens with a diameter of 12.7mm and a focal length of 20.0mm, sourced from the reputable optical vendor, Edmund Optics. This lens is uncoated, which means it does not have any additional layers to enhance light transmission or protect the surface.
The lens's geometry is characterized by a thickness of 1.62mm at the edge and 3.8mm at the center. The radius of curvature (R1) is 10.34mm, and the back focal length (BFL) is 17.49mm. The lens is made of N-BK7 Schott, a popular optical glass due to its excellent optical properties and versatility.
The lens is designed to work with a wavelength of 587.6nm, making it suitable for applications that use yellow-green light, such as certain types of fluorescence microscopy or specific laser systems.
Please note that the lens is spherical, meaning it has a curved surface, which can cause spherical aberration in some applications. However, this type of lens is commonly used in various optical systems due to its simplicity and cost-effectiveness.
