48-645 3.0mm Dia. x 7.5mm FL; Plano-Convex Lens Uncoated

The 48-645 3.0mm Dia. x 7.5mm FL Plano-Convex Lens Uncoated is a high-quality optical component sourced from Edmund Optics. This lens, with a diameter of 3.0mm and a focal length of 7.5mm, is a spherical lens of the Plano-Convex type, featuring a circular base shape.

The lens's geometry includes a thickness of 1.2mm at the edge and 1.5mm at the center, with an effective focal length (EFL) of 7.5mm. The radius of curvature (R1) is 3.88mm, and the back focal length (BFL) is 6.51mm. The lens's inner and outer radii are both 0mm, indicating a flat surface on the non-curved side.

This lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and wide transparency range. The lens is uncoated, which means it does not have any anti-reflective or other coatings applied to its surfaces. This can result in higher reflective losses but may be suitable for certain applications where specific coatings are not required.

The lens is designed to operate at a wavelength of 587.6nm, making it suitable for a wide range of applications in the visible light spectrum. Please note that the lens's performance can vary depending on the specific conditions of its use, including the light source's wavelength, the distance from the lens, and the angle of incidence.
