The 45-380 9.0mm Dia. x -9 FL is a high-quality plano-concave lens sourced from Edmund Optics. This lens, with its base shape of a circle, is designed for use in a wide range of optical applications. The lens is uncoated, offering users the flexibility to apply their preferred coating based on their specific requirements.
The lens features a diameter of 9.0mm, providing a substantial surface area for light transmission. The thickness at the edge of the lens is 3.63mm, while the center thickness is 2.25mm, offering a sleek and compact design. The effective focal length (EFL) of the lens is -9.0mm, making it suitable for applications that require a negative focal length.
The lens's first radius of curvature (R1) is -7.07mm, and the back focal length (BFL) is -10.21mm. The lens does not have an inner radius or an outer radius, indicating a simple, straightforward design.
The lens is made from n-sf11 Schott, a high-index glass with excellent optical properties. It is designed to work with a wavelength of 587.6nm, making it suitable for applications that use this specific wavelength.
