LA4874 UV Fused Silica Plano-Convex Lens; Dia:1 in; f=150.5 mm Uncoated

The LA4874 UV Fused Silica Plano-Convex Lens is a high-quality optical component designed for use in a wide range of applications. Manufactured by Thorlabs, a leading vendor in the field of optical components, this lens boasts a diameter of 1 inch and a focal length of 150.5 mm, making it a versatile choice for many setups.

The lens is made from UV Fused Silica, a material known for its excellent transmission properties across a broad spectrum, including the ultraviolet range. This makes the LA4874 particularly suitable for applications where high transmittance in the UV range is required.

The lens geometry is that of a Plano-Convex design, with a spherical surface and a flat base. The spherical surface has a radius of curvature of 69 mm, while the back focal length is 148.4 mm. The lens has a thickness of 2 mm at the edge and 3.2 mm at the center, providing robustness and stability.

The LA4874 is uncoated, meaning it does not have any additional layers applied to its surface to alter its optical properties. This can be beneficial in certain applications where a natural lens surface is preferred. However, it's important to note that uncoated lenses may be more susceptible to environmental factors such as dust and moisture, and may also exhibit higher levels of reflection.

According to the vendor's website, the LA4874 is currently in stock, making it readily available for immediate use. The website also provides further technical specifications and application notes, which can be valuable resources for those considering this lens for their optical system.
