G052304400 8 mm Dia. N-BK7 Mounted Plano-Concave Lens; EFL=-8mm
The G052304400 is a plano-concave lens with an 8 mm diameter, manufactured by Qioptiq Photonics. This lens is made from N-BK7, a popular optical glass type known for its excellent optical properties and versatility. The lens has a center thickness of 1 mm and an effective focal length (EFL) of -8 mm, making it suitable for applications that require negative focal lengths.
The lens's geometry includes a radius of curvature (R1) of -4.134 mm for the concave surface. The inner and outer radii are both zero, indicating that the lens has a flat outer surface. This lens is coated with Qio Silver RAGV 45 on both the front and back surfaces, which is a broadband anti-reflection coating designed for use in the visible spectrum, specifically at a wavelength of 588 nm.
The lens is spherical in shape, which is the most common type of lens surface. Spherical lenses are easy to manufacture and provide good image quality, making them a popular choice for many optical applications. This lens is mounted, which means it is ready to be integrated into optical systems without the need for additional mounting hardware.
