89-061 20.0mm Dia. x 70.0mm 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 20.0mm. The lens has a thickness of 1.59mm at the edge and 3.0mm at the center. The effective focal length (EFL) of this lens is 70.0mm, making it suitable for a variety of optical applications.
The lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and wide transparency range. The inner and outer radii of the lens are 0mm, indicating a uniform curvature throughout.
The lens is coated with Edmund Optics Las V-Coat 1550, a specialized coating designed for use in the 1550nm wavelength range. This coating is applied to both the front and back surfaces of the lens, enhancing its performance in laser applications.
