LB1607 N-BK7 Bi-Convex Lens; Dia:2 in; f=175.0 mm Uncoated

The LB1607 N-BK7 Bi-Convex Lens is a high-quality optical component sourced from Thorlabs, a leading vendor in the field of precision photonics. This lens, with a diameter of 2 inches and a focal length of 175.0 mm, is designed for use in a wide range of optical systems, including imaging, beam shaping, and laser applications.

The lens is made from N-BK7, a type of borosilicate glass known for its excellent optical properties. This material is characterized by a high refractive index and low dispersion, making it ideal for applications that require high-precision optical performance. The lens is uncoated, which means it does not have any additional layers to enhance its optical properties. However, uncoated lenses can still provide excellent performance in many applications, especially where high transmission and low reflectivity are not critical.

The geometry of the lens is spherical, with both surfaces curved outwards. This bi-convex design provides a number of benefits, including a wide field of view, low spherical aberration, and a long focal length. The lens has a central thickness of 6.6 mm and an edge thickness of 3 mm, providing a robust and durable structure.

The lens is designed to work at a wavelength of 587.6 nm, which falls within the visible spectrum. This makes it suitable for use in a wide range of applications that involve visible light, such as microscopy, spectroscopy, and laser-based systems.
