The 88-774 is a 3.0mm diameter, 3.0mm focal length plano-convex lens, featuring a YAG-BBAR coating optimized for the 500-1100nm wavelength range. This lens, sourced from Edmund Optics, is a spherical lens with a base shape of a circle, designed for general-purpose use in various optical systems.
The lens has a thickness of 1.46mm at the edge and 2mm at the center, providing a balanced structure for efficient light transmission. The effective focal length (EFL) is 3mm, which, combined with the focal length, results in a back focal length (BFL) of 1.88mm. The inner and outer radii are both 0mm, indicating a uniform curvature throughout the lens.
The lens is made of n-SF11 Schott material, a high index glass with excellent transmittance in the visible and near-infrared regions. The YAG-BBAR coating on both the front and back surfaces further enhances the lens' performance by reducing reflection and increasing transmission within the specified wavelength range.
