SLB-25.4-60P 25.4 mm Dia. x 60.0 mm FL; Plano-Convex Lens Uncoated

The SLB-25.4-60P is a Plano-Convex lens with a diameter of 25.4 mm and a focal length of 60.0 mm. This lens is sourced from OptoSigma, a renowned vendor in the optical industry. The lens is made of n-BK7 Schott, a high-quality optical glass known for its excellent transparency and low auto-fluorescence.

The lens geometry is characterized by its edge thickness of 1.9 mm and center thickness of 4.6 mm. The effective focal length (EFL) is 60 mm, and the radius of curvature (R1) is 31.14 mm. The back focal length (BFL) is 57 mm, and both the inner and outer radii are 0 mm.

This lens is uncoated, which means it does not have any anti-reflective coatings. While this may result in a higher reflectance at the air-glass interfaces, it also means the lens is more cost-effective and versatile, as it can be used in a wide range of applications without the risk of coating-specific limitations.

The lens is designed to work with a wavelength of 546.1 nm, making it suitable for applications that use this wavelength, such as certain types of fluorescence microscopy. The lens shape is spherical, which is a common choice due to its ease of manufacturing and good image quality.
