67-498 12.0mm Dia. x 30.0mm 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 and a diameter of 12mm. The lens has a thickness of 1.58mm at the edge and 3.5mm at the center, with an effective focal length (EFL) of 20mm. The radius of curvature (R1) is 10.34mm, and the back focal length (BFL) is 17.69mm. The lens does not have an inner or outer radius.
The lens is made of N-BK7 Schott material, a popular choice for its high refractive index and low dispersion. It is designed to work with a wavelength of 587.6nm. The lens features a coating on both the front and back surfaces with the EDM NIR-II STD curve, which is specifically designed for use in the near-infrared (NIR) spectrum, enhancing its performance in the 750-1550nm range.
This lens is sourced from Edmund Optics, a leading supplier of optical components. The item data indicates that it is currently in stock, ensuring quick delivery for your optical system needs.
