The 38-411-INK 12.7mm Dia. x 40.0mm FL; NIR II; Inked; Plano-Convex Lens is a specialized optical component designed for near-infrared (NIR) applications, specifically in the 750-1550nm range. This lens is sourced from Edmund Optics, a renowned vendor in the optical industry.
The lens is of the Spherical type, with a Sub Type of Spherical Lens (Plano-Convex). It features a circular Base Shape with a diameter of 12.7mm. The lens has a thickness of 1.95mm at the edge and 3mm at the center, providing a robust structure for various applications. The effective focal length (EFL) of this lens is 38.1mm, making it suitable for medium to long-range focus requirements.
The lens's front and back surfaces are coated with the "edm nir-ii std curve", a specialized coating that enhances its performance in the NIR spectrum. This coating ensures high transmission rates and reduces unwanted reflections, making it ideal for NIR applications.
The lens is made from N-BK7 Schott, a high-quality optical glass known for its excellent optical properties and durability. The lens's geometry, including its inner and outer radii, is optimized for NIR applications, further enhancing its performance.
