22-708 100mm Dia. N-BK7 Precision Aspheric Lens; EFL=100mm; NA=0.5 BBAR 425-675nm

This is a high-quality 100mm diameter N-BK7 aspheric lens, offered by the renowned optical vendor, Edmund Optics. The lens boasts a 0.5 numerical aperture (NA) and features broadband anti-reflection (BBAR) coating for the visible spectrum, specifically designed for the 425-675nm range.

The lens's geometry is meticulously designed, with an inner radius of 0 and an outer radius also set at 0. The diameter measures 100mm, and the edge thickness is 5.9mm. The effective focal length (EFL) is 100mm, and the radius of curvature (R1) is 51.68mm. The lens's back focal length (BFL) is 78.18mm, and the center thickness is 33.1mm. The lens's conic constant (K1) is -1, and higher-order aspheric coefficients (K2, K3, etc.) are not provided, indicating a high level of precision in the lens's design and manufacturing.

The lens's coating is another notable feature. The front and back surfaces are coated with BBAR coating, designed for the 425-675nm range, which reduces reflection and increases transmission in the visible spectrum. This coating ensures optimal performance in applications where high transmission and low reflection are required.

The lens is available for purchase directly from the Edmund Optics website, and the link provided is valid and indicates that the lens is in stock. This lens is a great choice for applications that require high precision, such as imaging systems, beam shaping, and other optical systems.
