G312327400 25.4 mm Dia. N-BK7 Plano-Convex Lens; EFL=500mm
The G312327400 is a Plano-Convex lens with a diameter of 25.4 mm, sourced from Qioptiq Photonics. This lens is designed for use in the visible light spectrum, specifically at a wavelength of 588 nm. The lens is made from N-BK7, a popular optical glass known for its excellent optical properties, high transmittance, and low auto-fluorescence.
The lens features a focal length of 500 mm, indicated by its Effective Focal Length (EFL). The EFL is a measure of the lens's ability to focus light and is a critical parameter in lens selection. This lens's EFL makes it suitable for applications requiring moderate to high magnification.
The lens has a center thickness of 4 mm and an edge thickness of 3.7 mm. The plano-convex shape, where one side is flat (plano) and the other side is curved (convex), allows for efficient light gathering and focusing. The inner and outer radii are 0 mm, indicating a sharply curved convex surface.
The lens is coated with Qio Silver RAGV 45 on both the front and back surfaces. This coating enhances the lens's durability and resistance to environmental factors, while also reducing surface reflections and improving light transmission.
