G063059322 22.4 mm Dia. N-BK7 Mounted Double-Concave Lens; EFL=-30mm 450-700nm

This is a G063059322 model double-concave lens, featuring a 22.4 mm diameter and a center thickness of 1.5 mm. The lens is made of N-BK7, a popular optical glass from Schott, known for its excellent optical properties and wide transparency range.

The lens has a negative focal length (EFL) of -30mm, making it suitable for use in various applications that require light convergence. The lens is designed to work optimally with light in the 450-700nm range, which covers the visible light spectrum, making it a versatile choice for many optical systems.

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 by reducing reflection and increasing transmission, thereby improving the overall efficiency of the optical system.

The lens's geometry is spherical, with both surfaces curved inward (concave). This design provides a wide field of view and low distortion, making it ideal for imaging applications. The lens is mounted, making it ready for immediate use in your optical system.
