67-461 6.0mm Dia. x 9.0mm FL; NIR II Coated; Plano-Convex Lens NIR II 750-1550nm
This is a 67-461 Plano-Convex Lens, a high-quality optical component sourced from Edmund Optics. The lens has a diameter of 6mm and a focal length of 9mm, making it a compact yet powerful option for various applications.
The lens is made from n-SF5 Schott, a material known for its excellent optical properties, particularly in the near-infrared (NIR) range. This is further enhanced by the NIR II coating on both the front and back surfaces, which is standard for this model. This coating is designed to optimize the lens' performance in the 750-1550nm wavelength range, making it ideal for NIR applications.
The lens' geometry is another notable feature. It has a thickness of 0.95mm at the edge, increasing to 1.75mm at the center. The inner and outer radii are 0, indicating a flat surface on the side opposite the curvature. The curvature itself has a radius of 6.05mm, and the back focal length is 7.95mm.
