39-510 25.4mm Dia. ZnSe Aspheric Lens; EFL=12.7mm; NA=1 BBAR 8-12µm
This is the 39-510 model from Edmund Optics, a 25.4mm diameter ZnSe Aspheric Lens with a focal length of 12.7mm and a broadband anti-reflection coating designed for the 8-12µm spectral range.
The lens is made of ZnSe (Zinc Selenide), a material with a high refractive index and dispersion, making it suitable for applications in the mid-infrared region. The aspheric design of the lens helps to reduce spherical aberration, a common issue in traditional spherical lenses, thereby improving the image quality.
The lens has a high numerical aperture (NA) of 1, which allows for a wide angle of view and high light-gathering capability. The inner and outer radii of the lens are 0, indicating a symmetrical design. The lens has a thickness of 1.83mm at the edge and 6mm at the center.
The lens is coated with a broadband anti-reflection coating, specifically designed for the 8-12µm spectral range. This coating reduces surface reflections, thereby improving the transmission of light through the lens. The coating is applied to both the front and back surfaces of the lens.
The lens is currently in stock and available for purchase through the Edmund Optics website.
