45-143 4.5mm Dia. x 4.5mm FL; Uncoated; Plano-Convex Lens
The 45-143 4.5mm Dia. x 4.5mm FL; Uncoated; Plano-Convex Lens is a high-quality optical component sourced from Edmund Optics. This lens, with a diameter of 4.5mm, is designed for use in a variety of optical systems, offering a focal length of 4.5mm and a base shape of circular.
The lens is uncoated, which means it does not have any anti-reflective or other coatings applied to its surface. This can be beneficial in certain applications where the natural properties of the lens material are desired. However, it's important to note that uncoated lenses can exhibit higher levels of reflection, which may affect the performance in high-light applications.
The geometry of the lens includes a thickness at the edge of 1.8mm and a thickness at the center of 2.59mm. The effective focal length (EFL) is 4.5mm, and the radius of curvature (R1) is 3.61mm. The back focal length (BFL) is 3.05mm, and both the inner and outer radii are 0mm, indicating a plano-convex design.
The lens is made from n-lasf44 Schott, a high-quality optical glass known for its excellent transmission properties and chemical resistance. It is designed to work optimally at a wavelength of 587.6nm.
