The LA4765 UV Fused Silica Plano-Convex Lens is a high-quality optical component sourced from Thorlabs. This lens, with a diameter of 0.5 inches, is designed for use in a wide range of applications that require excellent optical performance.
The lens is spherical in shape, with a base shape of a circle. It features a plano-convex geometry, meaning one side is flat (plano) and the other side is curved (convex). This geometry is often used to minimize spherical aberration, a common issue in optical systems. The lens has a center thickness of 2.7 mm and an edge thickness of 1.8 mm, providing structural integrity and stability.
The LA4765 has an effective focal length (EFL) of 50.2 mm, which is the distance from the lens's center to the focal point. This EFL, combined with the lens's diameter, determines the lens's field of view and its ability to focus light. The lens's back focal length (BFL) is 48.3 mm, which is the distance from the lens's rear surface to its focal point.
This lens is made of UV Fused Silica, a material known for its high transparency in the ultraviolet region of the spectrum. The material is identified as "uvfs mal- 1965" in the item data. This makes the LA4765 an excellent choice for applications that require UV transmission, such as UV curing, fluorescence microscopy, and UV spectroscopy.
The lens is uncoated, meaning it does not have any anti-reflective or other coatings. While coatings can enhance a lens's performance by reducing reflections, increasing transmission, or providing other benefits, uncoated lenses can be a more cost-effective choice, especially for applications where such enhancements are not necessary.
