45-978 3.0mm Dia. x 9.0mm FL; Telecom-NIR Coated; Plano-Convex Lens
The 45-978 is a Plano-Convex Spherical Lens with a diameter of 3.0mm and a focal length of 9.0mm, sourced from Edmund Optics. This lens is designed for use in the telecom-NIR (near-infrared) spectrum, with a coating on both the front and back surfaces that enhances its performance in this specific wavelength range.
The lens's geometry includes a thickness of 1.25mm at the edge and 1.5mm at the center, with an effective focal length (EFL) of 9.01mm. The radius of curvature for the first surface (R1) is 4.65mm, and the back focal length (BFL) is 8.01mm. The lens is made from n-BK7 Schott, a popular optical glass due to its excellent optical properties and versatility.
The coating on the lens, edm d telecom-nir yy, is specifically designed for use in the telecom-NIR spectrum. It enhances the lens's performance in this wavelength range, providing improved transmission and reduced reflection.
This lens is currently in stock and available for immediate purchase, making it an ideal choice for users looking for a high-quality, telecom-NIR lens for their optical systems.
