89-006 20.0mm Dia. x 35.0mm FL; Plano-Convex Lens Laser V-Coat 633nm

The 89-006 is a Plano-Convex spherical lens, part of the extensive catalog of optical elements sourced from Edmund Optics. This lens boasts a diameter of 20.0mm and a focal length of 35.0mm, making it suitable for a wide range of applications.

The lens is made from n-BK7 Schott, a high-quality optical glass known for its excellent transparency and low dispersion. This material ensures high-quality imaging and minimal chromatic aberration.

The lens features a front and back coating of edm las v-coat 633, a specialized coating designed for laser applications at a wavelength of 633nm. This coating enhances the lens's durability and performance, reducing reflection and increasing transmission.

The geometry of the lens includes a thickness of 1.48mm at the edge and 4.5mm at the center. The inner and outer radii are 0, indicating a circular shape. The lens's effective focal length (EFL) is 35.0mm, and the back focal length (BFL) is 32.04mm. The radius of curvature (R1) is 18.09mm.
