68-008 9mm Dia. x -9mm FL; NIR II Coated; Double-Concave Lens 750-1550nm

The 68-008 is a high-quality double-concave lens, boasting a 9mm diameter and a focal length of -9mm. This lens is sourced from Edmund Optics, a renowned vendor known for their extensive catalog of optical elements. The lens is designed for use within the near-infrared (NIR) spectrum, specifically between 750nm and 1550nm, making it ideal for a wide range of applications in this spectral range.

The lens is constructed from n-sf11 Schott, a high-index glass material that offers excellent optical performance. The double-concave design, characterized by its negative focal length, is particularly useful in imaging systems where a reduced image size is desired. The lens features a standard edge thickness of 3.48mm and a center thickness of 2.25mm, providing a robust and durable structure.

The 68-008 lens is coated with Edmund Optics' NIR-II standard curve coating on both the front and back surfaces. This coating is specifically designed to enhance performance within the NIR spectrum, ensuring optimal transmission and minimal reflection. The coating is applied using a precise and controlled process, ensuring consistent and reliable performance.
