67-521 15.0mm Dia. x 45.0mm FL; NIR II Coated; Plano-Convex Lens NIR II 750-1550nm

This is a 15.0mm diameter, 45.0mm focal length plano-convex lens, specifically designed for use in the near-infrared (NIR) spectrum, covering the wavelength range of 750-1550nm. The lens is sourced from Edmund Optics, a reputable vendor known for their high-quality optical components.

The lens is made from N-BK7 Schott glass, a popular material for optical elements due to its excellent optical properties and versatility. The plano-convex geometry, where one side is flat and the other is curved, is a common design for lenses, providing a simple yet effective way to focus light.

The lens features a standard curvature coating on both the front and back surfaces, specifically the EDM NIR-II coating. This coating is designed to enhance the lens' performance in the NIR spectrum, reducing reflections and increasing transmission in this wavelength range.

The lens has a center thickness of 3.8mm and an edge thickness of 1.4mm, providing a good balance between robustness and optical performance. The effective focal length (EFL) is 25mm, which is the distance from the lens's principal point to the focal point. The front radius of curvature is 12.92mm, and the back focal length is 22.5mm.

According to the provided data, this lens is in stock, making it readily available for immediate use in your optical systems. With its high-quality NIR coating and reliable N-BK7 Schott glass construction, this plano-convex lens is an excellent choice for applications that require efficient light transmission and focusing in the near-infrared spectrum.
