The 45-503-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 20.0mm, is designed for use in the visible to near-infrared (VIS-NIR) spectrum, specifically catering to the wavelength of 587.6nm.
The lens has a center thickness of 3.0mm and an edge thickness of 1.59mm, providing a base shape that is circular. The effective focal length (EFL) of this lens is 70.0mm, making it suitable for various optical applications. The front and back surfaces of the lens are coated with "edm visnir0sp2002000", a coating specifically designed for VIS-NIR applications, enhancing its performance in this spectrum.
The lens's geometry includes an inner radius of 0mm and an outer radius of 0mm. The front surface radius (R1) is 36.18mm, and the back focal length (BFL) is 68.03mm. The material used for this lens is n-bk7 schott, a popular choice for its high refractive index and low dispersion.
The lens is currently in stock and available for immediate purchase. For more detailed information, please refer to the vendor's website at https://www.edmundoptics.com/f/vis-nir-coated-plano-convex-pcx-lenses/12278/.
