66-294 25.4mm Dia x 150.0mm EFL; Uncoated; Silicon Plano-Convex Lens
The 66-294 is a Plano-Convex lens with a diameter of 25.4mm and an effective focal length (EFL) of 150.0mm. This lens is sourced from Edmund Optics, a leading vendor in the optical industry. The lens is made of silicon, specifically identified as "silicon sal vil 1957" in the material database.
The lens's geometry is characterized by its diameter, thickness at the edge (2mm), and thickness at the center (2.2mm). The lens's design is spherical, with an inner radius of 0mm and an outer radius of 0mm, indicating a plano surface on one side and a curved surface on the other. The curvature of the curved surface is defined by a radius of 363.54mm.
This lens is uncoated, meaning it does not have any anti-reflective or other surface coatings. This may result in higher reflective losses and lower transmission compared to coated lenses. However, uncoated lenses are often chosen for their simplicity, cost-effectiveness, and compatibility with a wide range of wavelengths, as is the case with the 66-294.
The lens is designed to operate at a wavelength of 10600nm. This makes it suitable for applications in the infrared spectrum, such as thermal imaging, night vision, and scientific research.
