68-005 6mm Dia. x -6mm FL; NIR II Coated; Double-Concave Lens 750-1550nm

The 68-005 is a high-quality double-concave lens, sourced from the renowned optical components manufacturer, Edmund Optics. This lens is designed for use in the near-infrared (NIR) spectrum, specifically for wavelengths between 750nm and 1550nm, making it suitable for a wide range of applications in fields such as biomedical imaging, spectroscopy, and optical communication.

The lens features a 6mm diameter and a focal length of -6mm, offering a high level of optical power. The double-concave design, characterized by its negative focal length and both surfaces curving inward, provides a unique optical behavior that is particularly useful in certain applications, such as beam expansion or collimation.

The lens is constructed from n-SF11 Schott glass, a material known for its excellent optical properties and durability. This glass has a high refractive index and low dispersion, making it ideal for use in NIR applications.

The 68-005 lens is coated with Edmund Optics' NIR-II standard curve coating on both the front and back surfaces. This coating is designed to enhance the lens' performance in the NIR spectrum, improving transmission and reducing reflection. The coating status is currently in stock, ensuring quick and reliable delivery.
