G314002322 8 mm Dia. N-BK7 Plano-Concave Lens; EFL=-8mm 450-700nm
This is a Plano-Concave lens, type N-BK7, with a diameter of 8 mm and a center thickness of 1 mm. The effective focal length (EFL) of this lens is -8 mm, making it a negative or diverging lens. The lens is designed to operate within the wavelength range of 450-700 nm, which covers the visible light spectrum.
The lens is made of N-BK7, a type of borosilicate glass known for its excellent optical properties, including high transmission in the visible and near-infrared regions, low autofluorescence, and high chemical durability. The lens has a spherical shape, with a radius of curvature of -4.134 mm for the concave surface.
The lens is coated with Qio Bbar Arb2visnbk7 on both the front and back surfaces. This coating is designed to enhance the lens's performance in the visible spectrum by reducing reflection and increasing transmission. The coating status is "in stock," indicating that the lens is readily available for purchase and use.
