LA1907-C N-BK7 Plano-Convex Lens; Dia:30.0 mm; f=150.0 mm ARC 1050-1700nm

The LA1907-C is a Plano-Convex lens, a type of spherical lens characterized by having one flat surface and one curved surface. This lens, sourced from the reputable vendor Thorlabs, boasts a diameter of 30.0 mm and a focal length of 150.0 mm, making it suitable for a wide range of optical applications.

The lens is made of N-BK7, a popular glass type in the optical industry due to its excellent optical properties. This material, also known as Schott glass, ensures high transmission and low dispersion, making it an ideal choice for various applications, including laser systems and imaging applications.

The LA1907-C features a coating on both the front and back surfaces, specifically the THo C Bbar coating. This anti-reflection coating is designed to minimize surface reflections, thereby enhancing the overall transmission of the lens. The coating is optimized for the wavelength of 632.8 nm, a common wavelength used in various applications such as spectroscopy and interferometry.

The lens has a center thickness of 3.1 mm and an edge thickness of 1.6 mm, providing a robust and durable structure. The inner and outer radii are 0 mm, indicating a uniform curvature across the lens surface. The back focal length is 147.5 mm, and the effective focal length is 150.0 mm, which are crucial specifications for determining the lens's focusing capabilities.
