The 87-925 is a spherical lens with a plano-convex base shape and a circular cross-section. This lens, sourced from Edmund Optics, boasts a 6mm diameter and a focal length of 18mm, making it suitable for a variety of applications. The lens is uncoated, providing a clear, unaltered view of the light passing through it.
The lens is fabricated from fused silica, a material with a high damage threshold, making it ideal for use in laser applications. The material's low autofluorescence ensures minimal background noise, enhancing the quality of the image. The lens's geometry includes an inner radius of 0mm and an outer radius of 0mm, indicating a uniform curvature throughout.
The lens's thickness at the edge is 1.44mm, while at the center, it measures 2mm. This variation in thickness contributes to the lens's ability to focus light effectively. The back focal length (BFL) of the lens is 16.62mm, a critical specification for determining the lens's position within an optical system.
The lens is designed to operate at a wavelength of 587.6nm, a common wavelength for visible light applications. This makes it suitable for use in applications such as microscopy, spectroscopy, and laser systems.
