LB1779 N-BK7 Bi-Convex Lens; Dia:1 in; f=300.0 mm Uncoated

The LB1779 N-BK7 Bi-Convex Lens is a high-quality optical component sourced from Thorlabs, a leading global vendor in the field of optics and photonics. This lens, with a diameter of 1 inch, is designed for use at a focal length of 300.0 mm, making it suitable for a wide range of applications that require precise focusing or imaging.

The lens is made of N-BK7, a type of borosilicate glass known for its excellent optical properties. This material is often used in high-precision applications due to its low coefficient of thermal expansion and high homogeneity. The N-BK7 designation indicates that this lens is made from Schott glass, a reputable manufacturer known for its high-quality optical materials.

The lens features a spherical shape, with both surfaces curved outwards, a design known as bi-convex. This shape is often used to reduce spherical aberration, a common issue in optical systems where light rays are not focused precisely on the optical axis. The lens has an effective focal length (EFL) of 300.0 mm, which is the distance from the lens to the point where light rays converge.

The lens has a center thickness of 2.5 mm and an edge thickness of 2 mm. The inner and outer radii are not specified, indicating that they are not critical to the lens's performance. The lens is uncoated, meaning it does not have any anti-reflective or other coatings applied to its surfaces. This may be suitable for applications where such coatings are not required or desirable.

According to Thorlabs' website, this lens is currently in stock, indicating that it is readily available for purchase and delivery. The website also provides further technical details and specifications, as well as options for customization and additional accessories.
