G313339322 25.4 mm Dia. N-BK7 Double-Concave Lens; EFL=-200mm 450-700nm

This is a G313339322 double-concave lens, sourced from Qioptiq Photonics, featuring a 25.4 mm diameter and a center thickness of 1.5 mm. The lens is designed with a concave-concave base shape and a symmetric geometry, making it suitable for a wide range of optical applications. The effective focal length (EFL) of this lens is -200mm, indicating its diverging nature. It is optimized for use within the wavelength range of 450-700nm, which includes the visible light spectrum.

The lens is made from N-BK7 glass, a popular choice in the optical industry due to its excellent optical properties and high Abbe number. This specific lens is unmounted, providing users with the flexibility to integrate it into their existing systems or designs.

The lens is coated with Qio Bbar Arb2visnbk7 on both the front and back surfaces. This coating enhances the lens's performance by reducing reflection and increasing transmission, thereby improving the overall efficiency and quality of the optical system.
