22-777 12.5mm Dia. Germanium Infrared Aspheric Lens; EFL=25mm; NA=0.25 BBAR 3-12µm

This is a high-quality 22-777 Germanium Infrared Aspheric Lens, sourced from the renowned optical vendor, Edmund Optics. The lens boasts a 12.5mm diameter and an effective focal length of 25mm, making it suitable for a wide range of infrared applications.

The lens is made from Germanium burnett, a material known for its excellent transmission properties in the infrared spectrum, particularly between 3µm and 12µm. This makes the lens ideal for use in applications such as thermal imaging, night vision, and other infrared-based technologies.

The lens features a high-quality BBAR (Broadband Anti-Reflection) coating on both the front and back surfaces. This coating helps to reduce surface reflections, thereby improving the overall transmission of the lens. The coating is designed to work across a broad spectrum, from 3µm to 12µm, ensuring optimal performance in a wide range of infrared applications.

The lens also features an aspheric design, which helps to reduce spherical aberration and improve the overall image quality. The aspheric shape is defined by the parameters r1=75.168, r2=0, k1=-0.9, and k2=0. The lens has a thickness of 2.74mm at the edge and 3mm at the center, providing a robust and durable construction.

The lens is currently in stock and available for immediate purchase. For more information, please refer to the vendor's website at https://www.edmundoptics.eu/p/125mm-dia-x-25mm-fl-3-12m-coated-ge-aspheric-lens/49005/.
