65-255 2.0mm Dia. x 3.0mm FL; Uncoated; Plano-Convex Lens
The 65-255 2.0mm Dia. x 3.0mm FL is an uncoated plano-convex lens sourced from Edmund Optics. This lens, with a base shape of a circle, is a spherical lens type, specifically designed for use in optical systems that require a convex lens surface.
The lens has a diameter of 2.0mm and a thickness of 0.6mm at the edge, while the center thickness is slightly greater at 0.8mm. The effective focal length (EFL) of this lens is 3.0mm, making it suitable for applications that require a moderate level of magnification or reduction.
The lens's curvature is defined by a radius of 2.55mm, and the back focal length (BFL) is 2.57mm. The lens does not have any coating, which means it is in its most basic form, offering no additional features such as anti-reflective properties or scratch resistance.
The lens is made from n-lasf9 Schott, a material known for its high optical quality and transmission in the visible spectrum. The lens is designed to work optimally at a wavelength of 587.6nm.
