39-544 12.7mm Dia. x 25.4mm FL; Coated; ZnSe Plano-Convex Lens BBAR 8-12µm

The 39-544 is a high-quality plano-convex lens offered by Edmund Optics, designed for use in the infrared spectrum with a wavelength of 10600nm. This lens boasts a 12.7mm diameter and a focal length of 25.4mm, making it suitable for a variety of applications that require precise optical performance.

The lens is fabricated from ZnSe (Zinc Selenide) material, which is known for its excellent transmission properties in the infrared region. The ZnSe connolly variant ensures high-quality performance and durability. The lens features a plano-convex geometry, with a front surface radius of 35.63mm, providing a smooth transition of light rays for optimal focus.

The 39-544 lens comes with a front and back broadband anti-reflection coating (BBAR), specifically designed for the 8-12µm wavelength range. This coating reduces surface reflections, enhancing the overall transmission of the lens and minimizing losses due to reflection.

The lens has a thickness of 1.93mm at the edge and 2.5mm at the center, providing a robust structure while maintaining a compact design. The lens is circular in shape, allowing for versatile integration into various optical systems.
