84-258 25.0mm Dia. x 75.0mm FL; Plano-Convex Lens Laser V-Coat 1550nm
This is a Plano-Convex Lens, a type of spherical lens, sourced from Edmund Optics. It is designed with a base shape of a circle and has a diameter of 25.0mm. The lens has a thickness of 2.43mm at the edge and 4.5mm at the center, with an effective focal length (EFL) of 75.0mm. The radius of curvature (R1) is 38.76mm, and the back focal length (BFL) is also 75.0mm.
The lens is made of N-BK7 Schott, a popular optical glass due to its excellent optical properties and wide transparency range. It is designed to operate at a wavelength of 1550nm.
The lens features a laser V-coat coating on both the front and back surfaces, specifically designed for 1550nm. This coating enhances the lens's performance in laser applications, providing improved transmission and reduced reflection.
Please note that the inner and outer radii of the lens are both 0, indicating that this lens does not have any special curvature or edge treatment.
