G063062400 22.4 mm Dia. N-BK7 Mounted Double-Concave Lens; EFL=-100mm
This is a G063062400 22.4 mm Dia. N-BK7 Mounted Double-Concave Lens, with a focal length (EFL) of -100mm, sourced from Qioptiq Photonics. The lens is mounted and features a base shape of a circle, with a diameter of 22.4mm and a center thickness of 1.5mm.
The lens is made of N-BK7 Schott glass, a popular choice for its high homogeneity and excellent optical transmission in the visible and near-infrared spectral range. The double-concave geometry of the lens is defined by radii of curvature of -104.41mm for the first surface and 104.41mm for the second surface. The lens does not have an inner or outer radius.
The lens is coated with Qio Silver RAGV 45 on both the front and back surfaces, enhancing its performance in specific applications. The coating is designed for high reflectivity at 45 degrees incidence angle.
This lens is suitable for use at a wavelength of 588nm. The item data does not provide information about the lens's clear aperture or its use in specific optical systems, so users should consider these factors when selecting this lens for their applications.
