33-379 40.0mm Dia. x 200.0mm FL; VIS-NIR Coated; Plano-Convex Lens VIS-NIR 400-1000nm
This is a Plano-Convex Lens, sourced from Edmund Optics, designed for use within the visible to near-infrared spectrum (VIS-NIR), specifically catering to wavelengths between 400 and 1000 nanometers. The lens boasts a diameter of 40.0mm and a focal length of 200.0mm, making it a versatile choice for various optical applications.
The lens is constructed from Schott's n-BK7 glass, a material well-known for its excellent optical properties, including a high Abbe number and low dispersion. This makes the lens suitable for applications requiring high image quality and minimal chromatic aberration.
The lens features a spherical shape, with a front surface radius of curvature of 103.36mm and a back focal length of 196.7mm. The edge thickness of the lens is 3.05mm, while the center thickness is 5mm, providing a robust and durable design.
The lens is coated with a VIS-NIR coating, specifically the 'edm visnir0sp2002000' coating, on both the front and back surfaces. This coating enhances the lens's performance within the VIS-NIR spectrum, improving transmission and reducing reflection.
