22-721 150mm Dia. N-BK7 Precision Aspheric Lens; EFL=150mm; NA=0.5 BBAR 600-1050nm
This is the 22-721 model from Edmund Optics, a 150mm Dia. N-BK7 Precision Aspheric Lens. The lens is designed with a 0.5 numerical aperture (NA) and features Broadband Anti-Reflection (BBAR) coating for the wavelength range of 600-1050nm.
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 base shape is circular, and it has a circular diameter of 150mm. The edge thickness of the lens is 7.51mm, and the effective focal length (EFL) is 150mm.
The lens's geometry is defined by several parameters. The inner radius is 0, and the outer radius is also 0. The lens's k1 value is -0.96, and the k2 value is 0. The lens's na value is 0.5, and it has an aspheric shape. The front and back of the lens are coated with BBAR 600-1050, ensuring high transmission and low reflectance across the specified wavelength range.
The lens is currently in stock and available for purchase through the Edmund Optics website. The link to the product page is provided in the item data for your convenience.
