G314002331 8 mm Dia. N-BK7 Plano-Concave Lens; EFL=-8mm
This is the G314002331 optical lens from Qioptiq Photonics, a Plano-Concave Spherical Lens with a diameter of 8 mm and a center thickness of 1 mm. The effective focal length (EFL) of this lens is -8 mm, making it a negative or diverging lens. The lens is made of N-BK7, a popular optical glass from Schott, known for its excellent optical properties and wide transparency range.
The lens's geometry includes an inner radius of 0 mm and an outer radius of 0 mm, indicating a simple plano-concave shape. The concave surface has a radius of curvature of -4.134 mm. The lens is unmounted, allowing users to integrate it into their optical systems as needed.
The lens is coated with Qio AL RALVIS AOI 45 on both the front and back surfaces. This coating enhances the lens's performance in specific wavelength ranges, in this case, 588 nm, by reducing reflection and improving transmission.
This lens is a great choice for applications that require a negative lens with a specific focal length and a small diameter. Its high-quality N-BK7 material and anti-reflection coating ensure excellent optical performance.
