48-647 2.5mm Dia. x 5.0mm FL; NIR I Coated; Plano-Convex Lens NIR I 600-1050nm

The 48-647 is a Plano-Convex Lens, a type of spherical lens, sourced from Edmund Optics. This lens has a base shape of a circle and a diameter of 2.5mm, making it suitable for a wide range of applications. The lens has a thickness of 0.61mm at the edge and 0.8mm at the center, providing a balanced structure for efficient light transmission.

The effective focal length (EFL) of this lens is 5mm, which is the distance from the lens's center to the principal point of the light beam it focuses. This EFL, combined with the lens's other dimensions, makes it ideal for applications requiring precise focusing of light.

The lens is made from n-lasf9 Schott, a high-quality optical material known for its excellent transmittance and durability. This material is particularly suitable for use in the near-infrared (NIR) region, specifically between 600 and 1050nm, making this lens a perfect choice for NIR applications.

The lens features a coating on both the front and back surfaces. This coating, identified as 'edm nir-i std curve', is designed to enhance the lens's performance in the NIR region. It ensures high transmittance and reduces reflection, thereby improving the efficiency and quality of the light passing through the lens.
