87-611 15.0mm Dia. x 20.0mm FL; Plano-Convex Lens Laser V-Coat 785nm
The 87-611 is a Plano-Convex spherical lens, a type of optical lens featuring one flat surface and one curved surface. This lens, with a diameter of 15.0mm and a focal length of 20.0mm, is sourced from Edmund Optics, a leading manufacturer in the field of optical components.
The lens is made from n-SF5 Schott, a high-quality optical glass known for its excellent transmission properties in the near-infrared region, making it ideal for applications involving 785nm wavelengths. The lens's geometry includes a thickness of 1.52mm at the edge and 3.8mm at the center, with an effective focal length (EFL) of 20.0mm. The radius of curvature for the first surface (R1) is 13.46mm, and the back focal length (BFL) is 17.74mm.
The 87-611 features a laser V-coat coating on both the front and back surfaces at 785nm. This coating enhances the lens's performance by reducing surface reflections and increasing transmission, thereby improving the overall efficiency and quality of the optical system in which it is used.
