45-915 9mm Dia. x -27 FL; VIS-NIR Coated; Plano-Concave Lens 400-1000nm
The 45-915 is a Plano-Concave Spherical Lens with a 9mm diameter, sourced from the reputable optical vendor, Edmund Optics. This lens is designed for use within the Visible to Near-Infrared (VIS-NIR) spectrum, specifically catering to wavelengths of 587.6nm.
The lens's geometry is characterized by its edge thickness of 3.42mm and center thickness of 3mm, with an Effective Focal Length (EFL) of -27mm. The front and back radii are -21.19mm and -28.68mm respectively, contributing to its plano-concave shape. The lens's Inner and Outer Radius are both 0mm, indicating a uniform curvature across its surface.
The lens is constructed from the high-quality material, n-SF11 from Schott, a leading manufacturer of optical glass. This material is known for its excellent optical properties, making it suitable for a wide range of applications.
The lens features a VIS-NIR coating, denoted as 'edm visnir0sp2002000', on both the front and back surfaces. This coating is designed to enhance the lens's performance within the VIS-NIR spectrum, reducing unwanted reflections and increasing transmission.
