LA1700-B N-BK7 Plano-Convex Lens; Dia:6.0 mm; f=30.0 mm ARC 650-1050nm

The LA1700-B 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 6.0 mm and a focal length of 30.0 mm, making it suitable for applications that require a compact, high-performance lens.

The lens geometry includes a thickness of 1.5 mm at the edge and 1.8 mm at the center, providing a robust structure while maintaining a low profile. The effective focal length (EFL) is 30.0 mm, and the radius of curvature (R1) is 15.5 mm. The back focal length (BFL) is 28.7 mm, and both the inner and outer radii are 0 mm, indicating a flat surface on the opposite side of the curved face.

The LA1700-B lens features broadband anti-reflection (BBAR) coatings on both the front and back surfaces, designed to operate over the wavelength range of 650-1050 nm. These coatings are engineered to reduce surface reflections, thereby increasing transmission and improving overall system performance.
