The 45-163 is a 30mm diameter, 50mm focal length uncoated spherical lens, specifically designed with a double-convex shape. This lens is sourced from the renowned optical vendor, Edmund Optics.
The lens's base shape is circular, and it features a geometry that includes an edge thickness of 2mm and a center thickness of 6.55mm. The effective focal length (EFL) is 50mm, and the radii of curvature are 50.56mm for the first surface and -50.56mm for the second surface. The back focal length (BFL) is 47.82mm, and both the inner and outer radii are 0mm.
The lens is made of n-BK7 Schott material, a popular choice for its high refractive index and low dispersion. It is designed to operate at a wavelength of 587.6nm. The lens's shape is spherical, a common choice for its ease of manufacturing and versatility.
Notably, this lens is uncoated, meaning it does not have any anti-reflective or other coatings applied to its surfaces. This can result in higher reflective losses and lower transmission, but it may be suitable for applications where such coatings are not required or desirable.
