12.7mm Dia. x 19.1mm FL NIR I Coated Plano-Convex Lens from Edmund Optics

This is a 12.7mm diameter by 19.1mm focal length plano-convex lens, coated with NIR I for the spectral range of 600-1050nm. The lens is sourced from the reputable optical components vendor, Edmund Optics.

The lens is made of n-BK7 Schott material, a popular choice for its high refractive index and low dispersion. The plano-convex geometry, where one side is flat and the other is curved, makes it suitable for a wide range of applications, including beam shaping, collimation, and focusing.

The lens has a center thickness of 4mm and an edge thickness of 1.69mm, providing a good balance between weight and optical performance. The front and back surfaces are coated with EDM NIR-I std curve, a broadband anti-reflection coating that enhances transmission in the near-infrared region.

The lens has a 9.87mm radius of curvature on the curved side, resulting in a back focal length of 16.46mm. The lens has no inner or outer radius, indicating it is a simple plano-convex lens without any additional features like threads or mounts.

According to the vendor's website, this lens is in stock, making it readily available for immediate use. The detailed specifications and the vendor's reputation make this lens a reliable choice for various optical applications in the near-infrared region.
