LB1630-A N-BK7 Bi-Convex Lens; Dia:2 in; f=100.0 mm ARC 350-700nm
The LB1630-A is a high-quality bi-convex lens manufactured by Thorlabs, a leading global supplier of photonics equipment. This lens boasts a diameter of 2 inches and a focal length of 100.0 mm, making it suitable for a wide range of optical applications.
The lens is made from N-BK7, a popular borosilicate glass known for its excellent optical properties. This material is characterized by a high refractive index and low dispersion, making it ideal for imaging and beam shaping applications. The lens features a clear aperture, providing a high transmission rate across the visible spectrum.
The LB1630-A is coated with Thorlabs' anti-reflection coating, which is designed to reduce surface reflections and increase transmission. This coating is optimized for the 350-700 nm range, ensuring high performance in visible light applications.
The lens geometry is spherical, with both surfaces curved inward. This design provides a strong focusing power, making the lens ideal for use in microscopy, beam shaping, and other applications where a tight focus is required. The lens has a thickness of 3 mm at the edge and 9.5 mm at the center, providing rigidity and durability.
