49-501 30mm Dia. x 75mm FL; NIR I Coated; Double-Convex Lens NIR I 600-1050nm
The 49-501 is a high-quality double-convex lens, sourced from the renowned optical component manufacturer, Edmund Optics. This lens is designed for use in the near-infrared (NIR) spectrum, specifically for wavelengths between 600 and 1050nm.
The lens boasts a diameter of 30mm and a focal length of 75mm, making it a versatile choice for a wide range of optical applications. The double-convex geometry, characterized by its two convex surfaces, provides excellent focusing capabilities and a wide field of view.
The lens is crafted from N-BK7 Schott glass, a material known for its excellent optical properties, including high transmittance and low dispersion. This ensures that the lens delivers sharp, clear images with minimal distortion.
The 49-501 is further enhanced by its NIR I coating, which is applied to both the front and back surfaces. This coating is specifically designed to optimize the lens' performance in the NIR spectrum, reducing reflection and increasing transmission. The coating is standard curve, ensuring consistent performance across a wide range of conditions.
