G311378322 18 mm Dia. N-BK7 Double-Convex Lens; EFL=16mm 450-700nm
This is the G311378322 model from Qioptiq Photonics, a high-quality double-convex lens with a diameter of 18 mm. The lens is made from N-BK7, a popular optical glass type known for its excellent optical properties, making it suitable for various applications.
The lens features a double-convex geometry, meaning it has two spherical surfaces that curve outwards. This design is often used to focus light, making it ideal for imaging and beam shaping applications. The lens has an effective focal length (EFL) of 16 mm, which is the distance from the lens's center to the point where it focuses light.
The lens's geometry includes a thickness of 1.1 mm at the edge and 7 mm at the center. The inner and outer radii are 0, indicating a symmetrical design. The lens's design is optimized for a wavelength of 587.6 nm, which falls within the visible light spectrum.
The lens comes with anti-reflective coatings on both the front and back surfaces. These coatings, specifically Qio Bbar Arb2visnbk7, are designed to reduce reflection and increase transmission, enhancing the lens's performance in various applications.
