45-514 25.0mm Dia. x 150.0mm FL; VIS-NIR Coated; Plano-Convex Lens VIS-NIR 400-1000nm
This is a Plano-Convex Lens, type 45-514, with a diameter of 25.0mm and a focal length of 150.0mm. The lens is sourced from the reputable vendor, Edmund Optics. It is designed for use within the visible to near-infrared spectrum, specifically catering to wavelengths between 400-1000nm.
The lens is made from the material n-bk7 schott, a popular choice for its high refractive index and low dispersion. This makes it ideal for imaging applications where high resolution and minimal chromatic aberration are required.
The lens features a spherical shape, with a front radius of curvature of 77.55mm and a back focal length of 147.81mm. The edge thickness of the lens is 2.49mm, while the center thickness is 3.5mm. This provides a good balance between optical performance and structural integrity.
The lens is coated with a broadband anti-reflection coating, specifically the edm visnir0sp2002000 coating, on both the front and back surfaces. This coating is designed to reduce surface reflections and increase transmission within the specified wavelength range.
