48-739 12.0mm Dia. x 48.0mm FL; NIR I Coated; Plano-Convex Lens NIR I 600-1050nm

This Plano-Convex Lens, model 48-739, is a high-quality optical component sourced from Edmund Optics. It is designed for use in the near-infrared (NIR) spectrum, specifically for wavelengths between 600 and 1050nm. The lens is made from Schott's n-BK7 glass, a popular material known for its excellent optical properties and wide transparency range.

The lens features a plano-convex geometry, meaning one side is flat (plano) while the other side is curved (convex). This design allows for efficient light collection and focusing. The lens has a diameter of 12.0mm and a focal length of 48.0mm, resulting in an f-number of approximately 4. The edge thickness of the lens is 1.76mm, while the center thickness is 2.5mm, providing robustness and durability.

The lens is coated with Edmund Optics' NIR I standard curve coating on both the front and back surfaces. This coating enhances the lens's performance in the NIR spectrum by reducing surface reflections and increasing transmission. The coating also provides excellent environmental resistance, ensuring the lens maintains its performance even in challenging conditions.
