LB4003 UV Fused Silica Bi-Convex Lens; Dia:0.5 in; f=30.0 mm Uncoated

The LB4003 is a high-quality UV Fused Silica Bi-Convex Lens, sourced from the renowned optical component manufacturer, Thorlabs. This lens boasts a diameter of 0.5 inches (12.7 mm) and a focal length of 30.0 mm, making it suitable for a wide range of optical applications.

The lens is designed with a Spherical shape, featuring two Convex surfaces, each with a radius of curvature of 27.1 mm. This design allows for efficient light gathering and focusing, making the lens ideal for imaging and beam shaping applications. The lens has an Effective Focal Length (EFL) of 30.0 mm and a Back Focal Length (BFL) of 28.8 mm, ensuring precise focus and alignment in your optical system.

The lens is made from UV Fused Silica, a material known for its excellent optical properties, including high transparency across a wide spectrum (from UV to NIR), low autofluorescence, and high resistance to thermal shock and chemical etching. The lens has a Center Thickness of 3.3 mm and an Edge Thickness of 1.8 mm, providing structural rigidity while minimizing unwanted optical effects.

The LB4003 is uncoated, offering a cost-effective solution for applications where coating is not required or preferred. However, for applications where high transmission, scratch resistance, or specific reflection properties are needed, Thorlabs offers a variety of coating options that can be customized according to your specific requirements.

According to the vendor's website, the LB4003 is currently in stock, ensuring quick delivery and minimal lead time. For more information, including technical specifications, pricing, and coating options, please refer to the vendor's website using the provided weblink.
