88-781 4.0mm Dia. x 4.0mm FL; YAG-BBAR Coated Plano-Convex Lens YAG-BBAR 500-1100nm
The 88-781 is a Plano-Convex Lens, a type of spherical lens, sourced from Edmund Optics. This lens has a diameter of 4.0mm and a focal length of 4.0mm, making it a compact and efficient optical component. The lens is made from n-lasf44 schott, a material known for its high optical quality and durability.
The lens features a YAG-BBAR coating on both the front and back surfaces. This coating, specifically designed for the wavelength range of 500-1100nm, enhances the lens's performance by reducing surface reflections and improving transmission. The coating ensures optimal light transmission, making this lens ideal for applications that require high-transmission performance.
The geometry of the lens is carefully designed with a thickness of 1.0mm at the edge and 1.7mm at the center. The lens's inner and outer radii are 0mm, indicating a flat surface on one side and a curved surface on the other. The radius of curvature (R1) is 3.21mm, and the back focal length (BFL) is 3.06mm. These parameters contribute to the lens's excellent optical performance.
