The LA1700-A 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 optical glass 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 use in systems where a long focal length is required.
The lens features an Anti-Reflection coating on both the front and back surfaces, designed to improve transmission and reduce unwanted reflections. This coating is optimized for use in the 350-700nm wavelength range, making it ideal for use with a wide range of visible light sources.
The lens geometry is spherical, with a radius of curvature of 15.5 mm on the convex surface. The lens has a thickness of 1.5 mm at the edge and 1.8 mm at the center, providing excellent mechanical stability. The lens is also AR-coated, which further enhances its optical performance.
In terms of its physical properties, the lens has an effective focal length (EFL) of 30.0 mm and a back focal length (BFL) of 28.7 mm. The inner and outer radii are both 0 mm, indicating a uniform curvature across the lens surface.
