G312006322 4 mm Dia. N-BK7 Plano-Convex Lens; EFL=4mm 450-700nm
This is a G312006322 4 mm Dia. N-BK7 Plano-Convex Lens, a high-quality optical component sourced from Qioptiq Photonics. The lens, which is currently in stock, is designed for use in the visible light spectrum, specifically between 450 and 700 nanometers.
The lens is of the Plano-Convex type, meaning it has one flat (plano) surface and one curved (convex) surface. This design is often used to focus or collimate light. The lens has a diameter of 4 mm and a thickness at the edge of 0.45 mm. The thickness at the center is 2 mm, providing a decent depth for light to pass through.
The effective focal length (EFL) of this lens is 4 mm, which is the distance from the lens's center to the point at which it focuses or collimates light. This short focal length makes it suitable for use in compact optical systems.
The lens is made from N-BK7, a type of glass commonly used in optical applications due to its excellent optical properties. The lens's front and back surfaces are coated with qio bbar arb2visnbk7, a coating that enhances its performance in the visible light spectrum.
