89-029 20.0mm Dia. x 100.0mm FL; Plano-Convex Lens Laser V-Coat 785nm

This is a Plano-Convex lens, type of spherical lens, with a circular base shape, sourced from the renowned optical vendor, Edmund Optics. The lens boasts a 20.0mm diameter and a 100.0mm focal length, 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 auto-fluorescence. This material makes the lens ideal for use in laser applications, as it can effectively transmit light in the 785nm wavelength range.

The lens features a V-coat 785nm coating on both the front and back surfaces. This coating is specifically designed to enhance the lens' performance in laser applications, providing improved durability, scratch resistance, and reflectivity. The coating also helps to reduce surface losses and increase the overall efficiency of the lens.

The geometry of the lens includes a thickness of 3.32mm at the edge and 4.3mm at the center. The lens' effective focal length (EFL) is 100mm, and the radius of curvature (R1) is 51.68mm. The back focal length (BFL) is 97.13mm, and both the inner and outer radii are 0mm.
