G063892331 25.4 mm Dia. N-BK7 Mounted Double-Concave Lens; EFL=-50mm
This is a G063892331 25.4 mm Dia. N-BK7 Mounted Double-Concave Lens, with a focal length (EFL) of -50mm, sourced from Qioptiq Photonics. The lens is currently in stock and available for purchase through their website.
The lens is of the Spherical type, specifically a Symmetric-concave-lenses-mounted-N-BK7, and has a base shape of Circular. It features a diameter of 25.4 mm and a center thickness of 1.5 mm. The inner and outer radii are both 0, and the radii of curvature are -52.33 mm for the first surface and 52.33 mm for the second surface.
The lens is made of N-BK7 Schott material, a popular choice for its high refractive index and low dispersion. It is designed to operate at a wavelength of 588 nm. The lens is coated with Qio AL RALVIS AOI 45 on both the front and back surfaces, which enhances its optical performance by reducing reflection and increasing transmission.
This lens is a Spherical type, which means it has a surface that is a portion of a sphere, with the center of the sphere being the vertex of the surface. This type of lens is commonly used in various optical systems due to its simple manufacturing process and good optical performance.
