G314304525 6 mm Dia. N-BK7 Plano-Concave Lens; EFL=-10mm 725-1050nm
This is a Plano-Concave lens, a type of spherical lens, sourced from Qioptiq Photonics. The lens has a 6 mm diameter and a center thickness of 1 mm. The effective focal length (EFL) of this lens is -10 mm, making it a negative or diverging lens.
The lens is made of N-BK7, a common type of borosilicate glass, which is known for its excellent optical properties and durability. The lens is unmounted, providing flexibility for users to mount it according to their specific requirements.
The lens is coated with Qio Bbar Arb2nirnbk7 on both the front and back surfaces. This coating enhances the lens's performance by reducing reflection and increasing transmission, making it suitable for use in a wide range of wavelengths, from 725 nm to 1050 nm.
The lens's geometry is defined by its inner and outer radii, both of which are 0 in this case, and its first radius of curvature (R1), which is -5.012 mm. This specific curvature contributes to the lens's diverging properties.
