G063058322 22.4 mm Dia. N-BK7 Mounted Double-Concave Lens; EFL=-20mm 450-700nm

This is a G063058322 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 -20mm, indicating its concave nature, which will cause light rays to diverge.

The lens is designed to operate within the wavelength range of 450-700nm, making it suitable for a wide range of applications, including but not limited to, fluorescence microscopy, machine vision, and other imaging systems. The lens's double-concave design, where both surfaces are concave, provides a high degree of optical power, making it an ideal choice for applications requiring strong focusing or imaging at a distance.

The lens comes with a broadband anti-reflection coating on both the front and back surfaces. This coating, identified as 'qio bbar arb2visnbk7', is designed to reduce surface reflections and increase transmission, thereby enhancing the overall performance of the lens in the specified wavelength range.
