The LA1765 N-BK7 Plano-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 30.0 mm, is designed for use in a wide range of optical systems, offering a focal length of 75.0 mm and a range of features that ensure excellent performance.
The lens is made from 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 its high homogeneity, which ensures consistent performance across a wide range of temperatures. The lens is uncoated, which means it does not have any additional layers applied to its surface to alter its optical properties.
The geometry of the lens is designed to optimize its performance in a variety of applications. It has a planoconvex shape, meaning one side is flat and the other is curved. This design allows for efficient light collection and focusing, making it ideal for use in imaging systems, beam shaping applications, and more. The lens has a thickness of 2.5 mm at the edge and 5.5 mm at the center, providing a robust and durable structure.
The LA1765 lens has a clear aperture, with no inner or outer radius, allowing for maximum light transmission. The effective focal length (EFL) of the lens is 75.0 mm, which is the distance from the lens's principal plane to the focal point. This EFL, combined with the lens's diameter, determines the lens's angular field of view and its magnification power.
In conclusion, the LA1765 N-BK7 Plano-Convex Lens is a versatile and high-performance optical component, ideal for a wide range of applications. Its uncoated N-BK7 surface, planoconvex geometry, and clear aperture ensure excellent light transmission and focusing, making it a reliable choice for any optical system.
