67-505 12.0mm Dia. x 84.0mm FL; NIR II Coated; Plano-Convex Lens NIR II 750-1550nm
This is a 12.0mm diameter, 84.0mm 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 the reputable optical vendor, Edmund Optics.
The lens is made from the high-quality material, N-BK7 Schott, which is known for its excellent optical properties and durability. The plano-convex geometry, where one side is flat and the other is curved, allows for efficient light collection and focusing. The lens has a center thickness of 2.5mm and an edge thickness of 1.91mm, providing a balance between weight and optical performance.
The lens features a standard NIR-II coating on both the front and back surfaces. This coating is designed to enhance the lens's performance in the NIR spectrum, reducing unwanted reflections and increasing transmission. The coating curve is the standard curve provided by Edmund Optics, ensuring consistent performance across their NIR-II product line.
The lens has an effective focal length (EFL) of 60mm, making it suitable for a variety of applications where high-resolution imaging in the NIR spectrum is required. The inner and outer radii are 0mm, indicating a uniform curvature across the lens surface.
