LA9977-E3 25.4 mm Dia. Germanium Plano-Convex Lens; EFL=75mm 7-12µm
The LA9977-E3 is a 25.4 mm diameter Germanium Plano-Convex lens, designed for use in the infrared spectrum with a wavelength of 10600 nm. This lens is sourced from Thorlabs, a reputable vendor known for their high-quality optical components.
The lens features an effective focal length (EFL) of 75mm, making it suitable for a variety of applications that require precise focusing and imaging. The plano-convex design, where one side is flat and the other is curved, allows for efficient light transmission and minimal spherical aberration.
The lens has a thickness of 3.6mm at the edge and 4mm at the center, providing structural integrity and stability. The inner radius is 0mm, indicating a sharply curved surface, while the outer radius is also 0mm, suggesting a flat outer surface.
The LA9977-E3 is coated with tho e3gearc700012000 on both the front and back surfaces. This coating enhances the lens's performance in the infrared spectrum, improving transmission and reducing reflection.
