G063063322 22.4 mm Dia. N-BK7 Mounted Double-Concave Lens; EFL=-150mm 450-700nm

This is a G063063322 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's effective focal length (EFL) is -150mm, making it a powerful tool for imaging applications where a reduced focal length is desired.

The lens is designed to transmit light in the spectral range of 450-700nm, which covers the visible light spectrum. This makes it suitable for a wide range of applications, including but not limited to, imaging, beam shaping, and laser systems. The lens's double-concave geometry, with radii of curvature R1=-156.22mm and R2=156.22mm, provides a unique optical power that can be harnessed in various optical systems.

The lens comes with a broadband anti-reflection coating on both the front and back surfaces. This coating, identified as 'qio bbar arb2visnbk7', is specifically designed to minimize surface reflections and increase transmission in the 450-700nm range. The coating ensures optimal performance by reducing losses and improving the overall efficiency of the optical system.
