LA1805-B N-BK7 Plano-Convex Lens; Dia:1 in; f=30.0 mm ARC 650-1050nm
The LA1805-B is a high-quality plano-convex lens from Thorlabs, designed for use in a wide range of optical applications. This lens is made from N-BK7, a popular glass type known for its excellent optical properties, and is Schott certified, ensuring a high level of quality and consistency.
The lens has a diameter of 1 inch (25.4 mm) and a focal length of 30.0 mm, making it suitable for use in systems where a long focal length is required. The lens is designed with a spherical surface, which helps to minimize spherical aberration and ensure optimal image quality.
The LA1805-B is coated with Thorlabs' BBAR coating, which is designed to reduce reflection and increase transmission over the 650-1050nm wavelength range. This coating helps to improve the overall efficiency of the optical system and reduces the need for additional anti-reflection components.
The lens has a thickness of 2 mm at the edge and 8.6 mm at the center, providing a robust and durable design. The inner and outer radii are both 0 mm, indicating a flat surface on the uncoated side of the lens.
