G314334322 12.7 mm Dia. N-BK7 Plano-Concave Lens; EFL=-200mm 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 -200mm, 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 borosilicate glass, which is known for its excellent optical properties and durability. The front and back surfaces of the lens are coated with qio bbar arb2visnbk7, a broadband anti-reflection coating designed for use in the visible spectrum. This coating helps to reduce surface reflections, improving the overall transmission of light through the lens.

The lens is unmounted, meaning it does not come with any housing or mounting hardware. This allows for flexibility in integration, but users should ensure they have appropriate mounting solutions to maintain the lens's alignment and prevent damage.
