65-279 1.5mm Dia. x 2.0mm FL; VIS 0° Coated; Plano-Convex Lens VIS 0° 425-675nm
The 65-279 is a Plano-Convex Lens, a type of spherical lens, sourced from Edmund Optics. This lens has a diameter of 1.5mm and a focal length of 2.0mm, making it suitable for a variety of optical applications. The lens is made from n-lasf9 Schott, a material known for its high refractive index and low dispersion, which contributes to superior image quality.
The lens features a standard VIS 0° coating on both the front and back surfaces. This coating enhances the lens's performance in the visible light spectrum, specifically between 425-675nm. The coating reduces surface reflections, thereby increasing transmission and improving overall image quality.
The geometry of the lens includes a thickness of 0.63mm at the edge and 0.8mm at the center. The inner radius is 0, while the outer radius is also 0, indicating a plano surface on one side and a curved surface on the other. The effective focal length (EFL) is 2mm, and the back focal length (BFL) is 1.57mm.
The 65-279 is currently in stock, according to the vendor's website. This lens is a reliable choice for those seeking high-quality optical performance in the visible light spectrum.
