G063874329 25.4 mm Dia. N-BK7 Mounted Plano-Concave Lens; EFL=-500mm 1064nm
This is a G063874329 Plano-Concave Lens, a high-quality optical component sourced from Qioptiq Photonics. The lens is mounted and features a base shape of a circle, with a diameter of 25.4 mm. The center thickness of the lens is 1.5 mm, and it has an effective focal length (EFL) of -500 mm at a wavelength of 1064 nm.
The lens is made of N-BK7, a popular glass type known for its excellent optical properties. The curvature of the lens is defined by a radius (R1) of -260.39 mm on the concave side. The inner and outer radii are both zero, indicating a uniform curvature.
The lens is coated with Qio HP Nbar ARHS-YAG on both the front and back surfaces. This coating enhances the lens's performance by reducing reflection and increasing transmission, particularly at the specified wavelength.
