LB1187-B N-BK7 Bi-Convex Lens; Dia:0.5 in; f=100.0 mm ARC 650-1050nm
The LB1187-B is a high-quality bi-convex lens from Thorlabs, designed with a base shape of a circle and a spherical geometry. This lens boasts a diameter of 12.7 millimeters and a thickness at the edge of 1.8 millimeters, while the center thickness measures 2.2 millimeters. The effective focal length (EFL) of this lens is 100 millimeters, and the back focal length (BFL) is 99.3 millimeters.
The lens is made of n-BK7 Schott, a popular optical glass known for its excellent optical properties. It is designed to work optimally with a wavelength of 633 nanometers. The lens features anti-reflection coatings on both the front and back surfaces, specifically the THORLABS BBAR coating, which is designed for the 650-1050 nanometer range. This coating helps to reduce surface reflections, thereby increasing the amount of light transmitted through the lens.
The LB1187-B is currently in stock and available for immediate purchase from the Thorlabs website. With its robust design and high-quality materials, this lens is an excellent choice for a wide range of optical applications.
