67-534 20.0mm Dia. x 35.0mm FL; NIR II Coated; Plano-Convex Lens NIR II 750-1550nm
The 67-534 is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens boasts a diameter of 20.0mm and a focal length of 35.0mm, making it a compact yet powerful optical component. The lens is made from n-sf11 Schott, a high-index glass with excellent transmittance in the near-infrared (NIR) region.
The lens features a plano-convex geometry, meaning one side is flat (plano) while the other is curved (convex). This design allows for efficient light collection and focusing. The lens's inner radius is 0mm, and the outer radius is also 0mm, indicating a symmetrical curvature. The thickness at the edge of the lens is 1mm, while the center thickness is 4.6mm, providing a balanced structure for optimal performance.
The 67-534 lens is coated with Edmund Optics' standard NIR-II coating on both the front and back surfaces. This coating enhances the lens's performance in the NIR region, specifically between 750nm and 1550nm, making it ideal for applications such as night vision, thermal imaging, and spectral analysis.
