LA1254-B N-BK7 Plano-Convex Lens; Dia:1 in; f=1500.0 mm ARC 650-1050nm
The LA1254-B 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 1 inch, is designed for use in a wide range of optical systems, particularly those operating within the wavelength range of 650-1050nm.
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, making it ideal for various applications such as imaging, beam shaping, and laser systems. The lens has a focal length of 1500mm, which is the distance between the lens and the point where it focuses light.
The LA1254-B lens is made from N-BK7, a popular glass type known for its excellent optical properties. This material ensures high transmission and low dispersion, which are crucial for maintaining image quality and reducing chromatic aberration.
The lens is coated with a broadband anti-reflection coating (ARC) on both the front and back surfaces. This coating, designed for the 650-1050nm range, significantly reduces surface reflections, thereby improving light transmission and enhancing the overall performance of the lens.
