LA1380 N-BK7 Plano-Convex Lens; Dia:2 in; f=500.0 mm Uncoated

The LA1380 N-BK7 Plano-Convex Lens is a high-quality optical component sourced from Thorlabs, a leading vendor in the field of optical equipment. This lens, with a diameter of 2 inches, is designed for use in a variety of applications that require precise optical control.

The lens is made of N-BK7, a type of borosilicate glass known for its excellent optical properties. This material is characterized by a low coefficient of thermal expansion, making it resistant to thermal shock. It also has a high homogeneity, low optical dispersion, and excellent transparency across a wide spectrum, from the ultraviolet to the infrared region.

The lens features a plano-convex geometry, meaning one side is flat (plano) while the other side is curved (convex). This design allows for efficient light collection and focusing. The radius of curvature of the convex surface is 257.5 mm, and the lens has a back focal length of 495.5 mm. The effective focal length (EFL) of the lens is 500 mm, which is the distance from the lens's principal plane to the focal point.

The lens has a central thickness of 4.3 mm and an edge thickness of 3 mm. Despite its thin profile, the lens is robust and durable, ensuring long-lasting performance. It is uncoated, meaning it does not have any anti-reflective or other surface treatments. However, it can be customized with various coatings upon request.

The LA1380 N-BK7 Plano-Convex Lens is currently in stock, according to the vendor's website. It is a versatile and reliable choice for various optical systems, offering high-quality performance and precision.
