SLB-25-170P 25.0 mm Dia. x 170.0 mm FL; Plano-Convex Lens Uncoated
The SLB-25-170P is a Plano-Convex lens with a diameter of 25.0 mm and a focal length of 170.0 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 2.0 mm and center thickness of 2.9 mm. The effective focal length (EFL) is 170.0 mm, and the radius of curvature (R1) is 88.23 mm. The back focal length (BFL) is 168.1 mm, and both the inner and outer radii are 0 mm.
The lens is uncoated, which means it does not have any anti-reflective or other coatings. This may result in higher reflective losses, but it also means that the lens can be used in a wider range of applications without the risk of coating-specific limitations.
The lens is designed for a wavelength of 546.1 nm, making it suitable for use in applications that use this wavelength, such as certain types of fluorescence microscopy.
