84-245 12.0mm Dia. x 42.0mm FL; Plano-Convex Lens Laser V-Coat 1550nm
The 84-245 is a Plano-Convex Spherical Lens, a type of spherical lens characterized by having one side flat and the other side curved outwards. This lens, sourced from Edmund Optics, boasts a diameter of 12.0mm and a focal length of 42.0mm, making it suitable for a wide range of optical applications.
The lens is made from n-BK7 Schott, a high-quality optical glass known for its excellent transparency and low dispersion. This material makes the lens an ideal choice for applications that require high image quality and minimal chromatic aberration.
The 84-245 features a laser-optimized V-coat for 1550nm, providing high transmission and low reflection at this wavelength. This coating enhances the lens' performance in laser-based applications, ensuring efficient light transmission and minimal loss due to reflection.
The lens has a central thickness of 2.7mm and an edge thickness of 1.85mm, providing a robust and durable design. The inner and outer radii are 0mm, indicating a uniform curvature across the lens surface.
