The 37-780 9.0mm Dia. x 25mm FL Plano-Convex Lens is an uncoated spherical lens sourced from Edmund Optics. This lens, with a base shape of a circle, is designed for use in various optical applications.
The lens has a diameter of 9.0mm and a thickness at the edge of 1.19mm, while the center thickness is 2.0mm. The effective focal length (EFL) of this lens is 25mm, making it suitable for applications that require a longer focal length. The radius of curvature for the first surface (R1) is 12.92mm, and the back focal length (BFL) is 23.68mm.
The lens is made of N-BK7 Schott, a popular optical glass due to its excellent optical properties and wide transparency range. It is designed to work at a wavelength of 587.6nm. The lens does not come with any coating, which may affect its performance in certain applications, particularly those requiring high transmission or specific surface properties.
Please note that the lens is uncoated, and additional coatings may be required depending on the specific application. Always refer to the vendor's specifications and recommendations for the best results.
