67-596 5mm Dia. x 5mm FL; NIR II Coated; Double-Convex Lens NIR II 750-1550nm
The 67-596 is a high-quality double-convex lens, designed and manufactured by Edmund Optics, a leading provider of optical components. This lens boasts a 5mm diameter and a focal length of 5mm, making it a versatile choice for a wide range of applications.
The lens is constructed from n-SF5 Schott, a material known for its excellent optical properties. This, combined with its double-convex geometry, ensures high-quality image formation and low distortion. The lens has an inner radius of 0mm and an outer radius of 0mm, further enhancing its optical performance.
The 67-596 features a standard NIR-II coating on both the front and back surfaces. This coating is specifically designed to enhance the lens' performance in the near-infrared spectrum, between 750nm and 1550nm. It provides improved transmission and reduced reflection, making it ideal for applications such as night vision, thermal imaging, and spectral analysis.
The lens has a thickness of 1.44mm at the edge and 2.5mm at the center. This robust construction ensures durability and longevity, even under heavy use. The back focal length of the lens is 4.19mm, providing flexibility in optical system design.
