67-984 6mm Dia. x -12 FL; NIR II Coated; Plano-Concave Lens 750-1550nm
The 67-984 is a plano-concave lens with a 6mm diameter, offering a focal length of -12 and a central thickness of 1.5mm, which gradually increases to 2.12mm at the edge. This lens is sourced from Edmund Optics, a reputable vendor known for its high-quality optical components.
The lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties, including a high Abbe number and low dispersion. This makes it an ideal choice for applications that require high image quality and precise light control.
The 67-984 is coated with Edmund Optics' NIR-II standard curve coating on both the front and back surfaces. This coating enhances the lens' performance in the near-infrared spectrum, specifically between 750nm and 1550nm, making it suitable for applications such as night vision, thermal imaging, and spectroscopy.
