16-278 10mm Dia. S-LAH64 NIR Aspheric Lens; EFL=8mm; NA=0.63 NIR-Plus 600-1050nm
The 16-278 is a high-quality aspheric lens offered by Edmund Optics, designed for use in the near-infrared (NIR) spectrum, specifically between 600 and 1050nm. This lens is characterized by its 10mm diameter and a numerical aperture (NA) of 0.63, making it a versatile choice for a variety of applications.
The lens is made from S-LAH64, a material from Ohara, which is known for its excellent optical properties in the NIR range. The aspheric design of the lens helps to reduce spherical aberration, improving the overall image quality. The inner and outer radii of the lens are 0mm, suggesting a symmetrical design that can further enhance the optical performance.
The lens has a focal length (EFL) of 8mm, which, combined with its high NA, makes it suitable for applications that require a wide field of view and high light-gathering capability. The thickness of the lens at the edge is 1.57mm, while the center thickness is 3.7mm, providing a good balance between optical performance and mechanical robustness.
The lens is coated with Edmund Optics' NIR-Plus coating, which is designed to enhance the transmission in the NIR range. This coating is applied to both the front and back surfaces of the lens, ensuring optimal performance regardless of the direction of light propagation.
