38-561-INK 35.0mm Dia. x 70.0mm FL; VIS-NIR; Inked; Plano-Convex Lens VIS-NIR 400-1000nm

This product is a plano-convex lens, sourced from the renowned optical component vendor, Edmund Optics. The lens boasts a diameter of 35.0mm and a focal length of 70.0mm, making it suitable for a wide range of applications. The lens is designed to operate within the visible to near-infrared spectrum, specifically between 400-1000nm, making it a versatile choice for various optical systems.

The lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and high Abbe number. This material ensures high transmittance and low dispersion, which are crucial for imaging and beam manipulation applications. The lens features a spherical shape, with a front radius of curvature of 36.18mm and a back focal length of 66.04mm.

The lens is coated with the EDM VIS-NIR 0SP2002000 coating on both the front and back surfaces. This anti-reflection coating is designed to reduce surface reflections and increase transmission within the specified spectral range. The coating also provides excellent environmental stability, ensuring the lens maintains its performance over time.
