G063060331 22.4 mm Dia. N-BK7 Mounted Double-Concave Lens; EFL=-40mm
This is a G063060331 model lens, a high-quality optical component manufactured by Qioptiq Photonics. The lens features a double-concave design with a base shape of a circle, making it suitable for a wide range of applications. The lens has a diameter of 22.4 mm and a center thickness of 1.5 mm, providing a robust and compact design.
The effective focal length (EFL) of this lens is -40mm, indicating that it is a negative or diverging lens. This type of lens is often used in applications where beam expansion or divergence is required. The lens's first radius of curvature (R1) is -41.867mm, and the second radius of curvature (R2) is 41.867mm, which contributes to its double-concave structure.
The lens is made of N-BK7 Schott glass, a common material in optical systems due to its excellent optical properties and high damage threshold. The glass has a refractive index of approximately 1.5168 at 588nm, which is the specified wavelength for this lens.
The lens is coated with Qio AL RALVIS AOI 45 on both the front and back surfaces. This coating enhances the lens's performance by reducing reflection and increasing transmission, thereby improving the overall efficiency of the optical system.
