LB4374-A UV Fused Silica Bi-Convex Lens; Dia:1 in; f=1000.0 mm ARC 350-700nm

The LB4374-A is a high-quality bi-convex lens, designed and manufactured by Thorlabs, a leading vendor in the optical industry. This lens, with a diameter of 1 inch, is specifically designed for use in the ultraviolet (UV) spectrum, with a focal length of 1000.0 mm, making it ideal for applications that require precise focusing and imaging in this spectral range.

The lens is made from UV fused silica, a material known for its excellent transparency in the UV region, low auto-fluorescence, and high resistance to thermal shock and chemical etching. This makes the LB4374-A a reliable choice for demanding UV applications.

The lens features a spherical geometry, with radii of curvature of 919.8 mm for the first surface and -919.8 mm for the second surface. This bi-convex design provides a large numerical aperture, enhancing the lens's light-gathering capability and improving its performance in high-resolution imaging applications.

The LB4374-A is coated with Thorlabs' anti-reflection coating, designed for the 350-700 nm range. This coating reduces surface reflections, thereby increasing the lens's transmission and improving its overall performance in UV applications.

In terms of dimensions, the lens has a thickness of 2 mm at the edge and 2.2 mm at the center. This ensures the lens's structural integrity while minimizing its weight and thickness.

According to the vendor's website, the LB4374-A is currently in stock, indicating its availability for immediate purchase and use. This, coupled with its impressive specifications, makes the LB4374-A a compelling choice for users seeking a high-performance UV lens for their optical systems.
