67-495 12.0mm Dia. x 18.0mm FL; NIR II Coated; Plano-Convex Lens NIR II 750-1550nm
This is a Plano-Convex Lens, sourced from the renowned optical components vendor, Edmund Optics. The lens is designed for use in the Near-Infrared (NIR) spectrum, specifically for the wavelength range of 750-1550nm, making it suitable for various applications in this spectrum.
The lens has a diameter of 12.0mm and a focal length of 18.0mm, indicated by the '12.0mm Dia. x 18.0mm FL' in its name. The 'Plano-Convex' term refers to the lens's geometry, where one side is flat (plano) and the other is curved (convex). This design is beneficial for specific optical applications where light needs to be focused or diverged.
The lens is made from N-SF11 Schott, a high-index glass with excellent optical properties, making it ideal for use in the NIR spectrum. The lens's front and back surfaces are coated with Edmund Optics' standard NIR-II coating, enhancing its performance in the NIR range.
The coating details are as follows: The front surface has an 'edm nir-ii std curve' coating, and the back surface also has an 'edm nir-ii std curve' coating. This coating helps reduce surface reflections and increases transmission, which is crucial for NIR applications.
