49-841 12.7mm Dia. x 19.1mm FL; Uncoated; Plano-Convex Lens

The 49-841 is a Plano-Convex lens with a diameter of 12.7mm and a focal length of 19.1mm, making it ideal for a wide range of optical applications. This lens is sourced from Edmund Optics, a reputable vendor known for their high-quality optical components.

The lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and high Abbe number. This material ensures high transmission in the visible spectrum, making it suitable for applications that require high light transmission.

The lens geometry is characterized by its base shape, which is circular, and its geometry, which includes a diameter of 12.7mm, a thickness edge of 1.69mm, and a thickness center of 4mm. The lens also has an effective focal length (EFL) of 19.1mm, a radius of curvature (R1) of 9.87mm, and a back focal length (BFL) of 16.46mm.

The lens does not come with any coating, which means it is uncoated. This may result in lower light transmission and higher susceptibility to environmental factors compared to coated lenses. However, uncoated lenses are often more cost-effective and can be a good choice for applications where high transmission is not critical.

The wavelength for this lens is 587.6nm, which is in the yellow-green region of the visible spectrum. This wavelength is often used in applications such as fluorescence microscopy and spectroscopy.
