45-515-INK 25.0mm Dia. x 175.0mm FL; VIS-NIR; Inked; Plano-Convex Lens VIS-NIR 400-1000nm

This product is a plano-convex lens, sourced from the reputable optical components vendor, Edmund Optics. The lens is designed for use within the visible to near-infrared spectrum, specifically catering to wavelengths between 400 and 1000 nanometers.

The lens boasts a diameter of 25.0mm and a focal length of 175.0mm, making it suitable for a variety of optical applications. The geometry of the lens is spherical, with a front surface radius of 90.47mm and a back focal length of 172.85mm. The edge thickness of the lens measures at 2.63mm, while the center thickness is 3.5mm, providing a robust and durable structure.

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 specified wavelength range, ensuring optimal light transmission and reducing unwanted reflections.

The material of the lens is n-BK7 Schott, a high-quality optical glass known for its excellent transmittance and low auto-fluorescence. This makes the lens ideal for use in applications where high light transmission and low background noise are critical.
