89-052 5.0mm Dia. x 20.0mm FL; Plano-Convex Lens Laser V-Coat 1550nm

The 89-052 is a Plano-Convex Spherical Lens, a type of spherical lens characterized by having one side flat and the other side curved. This particular model has a diameter of 5.0mm and a focal length of 20.0mm, making it suitable for a wide range of optical applications.

The lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and high Abbe number. This material ensures high transmittance and low dispersion, making it ideal for use in laser applications.

The lens features a laser-optimized V-coat coating on both the front and back surfaces. This coating, specifically designed for 1550nm wavelength, enhances the lens's performance by reducing reflection and increasing transmission. The coating's status is "in stock", indicating its immediate availability.

The geometry of the lens includes a thickness of 1.19mm at the edge and 1.5mm at the center. The inner and outer radii are both 0, indicating a simple spherical shape. The lens's effective focal length (EFL) is 20.0mm, and the back focal length (BFL) is 19.02mm. The radius of curvature (R1) is 10.34mm.
