G314335322 12.7 mm Dia. N-BK7 Plano-Concave Lens; EFL=-500mm 450-700nm
This is a Plano-Concave lens, a type of spherical lens, sourced from Qioptiq Photonics. The lens has a diameter of 12.7 mm and a center thickness of 1.5 mm. The effective focal length (EFL) of this lens is -500mm, making it a negative or diverging lens. This particular lens is designed to operate within the wavelength range of 450-700nm, which covers the visible light spectrum.
The lens is made of N-BK7, a common type of glass used in optical applications. This material is known for its excellent optical properties, including a high Abbe number and low dispersion. The lens's front and back surfaces are coated with "qio bbar arb2visnbk7", a coating that enhances its performance in the visible light spectrum.
The lens's geometry is such that it has a concave surface and a flat surface, with the concave surface having a radius of curvature of -260.39mm. The lens is unmounted, meaning it does not come with any housing or mounting mechanism.
