LA1074-633 N-BK7 Plano-Convex Lens; Dia:0.5 in; f=20.0 mm 633nm V-Coat
The LA1074-633 is a high-quality Plano-Convex lens from Thorlabs, designed for use in a wide range of optical applications. This lens is fabricated from N-BK7 Schott glass, a popular material known for its excellent optical properties and versatility.
The lens has a diameter of 0.5 inches (12.7 mm) and a focal length of 20.0 mm, making it suitable for use in systems where a long focal length is required. The lens's geometry includes a thickness of 1.8 mm at the edge and 4 mm at the center, providing a solid structure and ensuring efficient light transmission.
The LA1074-633 features a front and back coating of tho 633 n-bk7 vc 633, which enhances its performance by reducing surface reflections and increasing transmission. This coating is specifically designed for use at a wavelength of 633 nm, making this lens ideal for applications that require high-transmission at this wavelength.
