69-449 25.0mm Dia. x 85.0mm FL; Plano-Convex Lens Laser V-Coat 633nm

The 69-449 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 25.0mm and a focal length of 85.0mm, making it suitable for a variety 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 ideal for use in laser applications, particularly those using a wavelength of 633nm.

The lens features a laser V-coat 633 coating on both the front and back surfaces. This coating enhances the lens's performance in laser applications by increasing its damage threshold and reducing reflections. The coating also helps to protect the lens from environmental factors, ensuring its longevity and durability.

The geometry of the lens includes a thickness of 2.48mm at the edge and 4.3mm at the center. The inner and outer radii are both 0mm, and the back focal length is 82.17mm. The effective focal length of the lens is 85.0mm.

This lens is available from Edmund Optics and is currently in stock, making it a readily available option for those in need of a high-quality, durable, and efficient optical component.
