G063058331 22.4 mm Dia. N-BK7 Mounted Double-Concave Lens; EFL=-20mm
This is a G063058331 model lens, a high-quality optical component manufactured by Qioptiq Photonics. The lens boasts a 22.4 mm diameter and is designed with a double-concave structure, making it a spherical lens of the concave-concave type. The lens is mounted, ensuring stability and ease of integration into optical systems.
The lens is made of N-BK7, a renowned optical glass from Schott, known for its excellent optical properties and versatility. The effective focal length (EFL) of this lens is -20mm, indicating its concave nature. The first radius of curvature (R1) is -20.833mm, and the second radius of curvature (R2) is 20.833mm, which are crucial specifications for understanding the lens's optical performance.
The lens is designed to operate at a wavelength of 588nm, making it suitable for applications that require high precision in this spectral range. It comes with a front and back coating of Qio AL RALVIS AOI 45, which enhances its optical performance by reducing reflection and increasing transmission.
