69-471 6.0mm Dia. x 72.0mm FL; Plano-Convex Lens Laser V-Coat 785nm
The 69-471 is a Plano-Convex Spherical Lens, sourced from Edmund Optics, with a diameter of 6mm and a focal length of 72mm, specifically designed for use with a 785nm wavelength. This lens boasts a front and back coating of edm las v-coat 785, ensuring high-quality performance and durability.
The lens's geometry includes a thickness edge of 1.48mm and a thickness center of 1.6mm, with an effective focal length (EFL) of 72mm. The radius of curvature (R1) is 37.22mm, and the back focal length (BFL) is 70.97mm. The lens is made from n-bk7 schott material, a popular choice for its high Abbe number and low dispersion.
This lens is designed for use in a variety of applications, including but not limited to, laser systems, optical imaging, and beam shaping. It is currently in stock, according to the vendor's website, making it a readily available option for your optical needs.
Please note that the lens's inner and outer radii are both 0, indicating a flat surface on the uncoated side. This feature, combined with its small diameter and long focal length, makes it an ideal choice for applications requiring a tight beam focus over a long distance.
