LB1475-C N-BK7 Bi-Convex Lens; Dia:1 in; f=750.0 mm ARC 1050-1700nm

The LB1475-C 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 1 inch, is designed for use in a wide range of applications that require precise focusing and imaging capabilities.

The lens is constructed from N-BK7, a popular glass type known for its excellent optical properties. This material, also known as BK7, is a borosilicate crown glass that offers a high refractive index and low dispersion, making it ideal for applications that require high-resolution imaging and low chromatic aberration.

The LB1475-C features a bi-convex geometry, meaning it has two spherical surfaces that are both convex, or outwardly curved. This design provides a strong focusing power, making the lens suitable for use in microscopy, beam shaping, and other applications where a tight focus is required.

The lens has a focal length of 750.0 mm, which is the distance between the lens and the point at which it focuses light. This long focal length makes the lens suitable for use in applications that require a large working distance, such as in some microscopy setups.

The lens is coated with a broadband anti-reflection coating, designed to reduce surface reflections and increase transmission across the 1050-1700nm wavelength range. This coating enhances the lens's performance in infrared applications, making it a versatile choice for a wide range of optical systems.
