67-526 18.0mm Dia. x 22.5mm FL; NIR II Coated; Plano-Convex Lens NIR II 750-1550nm
This is a Plano-Convex lens, type of spherical lens with a circular base shape, specifically designed for use in the near-infrared (NIR) spectrum. The lens is sourced from Edmund Optics, a leading vendor in the optical industry, and is currently in stock.
The lens has a diameter of 18.0mm and a focal length of 22.5mm, resulting in an f-number of 1.25. The edge thickness of the lens is 1.1mm, while the center thickness is 1.83mm. The effective focal length (EFL) of the lens is 75mm, and the radius of curvature (R1) is 38.76mm. The back focal length (BFL) is 73.79mm. The lens does not have any inner or outer radius specified.
The lens is made of N-BK7 Schott, a popular optical glass due to its excellent optical properties and high Abbe number. It is designed to work optimally at a wavelength of 587.6nm.
The lens features a coating on both the front and back surfaces. This coating, identified as 'edm nir-ii std curve', is specifically designed for use in the NIR spectrum, enhancing the lens' performance in the 750-1550nm range.
