LA4984-UV UV Fused Silica Plano-Convex Lens; Dia:2 in; f=200.7 mm ARC 245-400nm

The LA4984-UV 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 2-inch diameter and a focal length of 200.7 mm, making it suitable for use in systems requiring precise focusing and imaging.

The lens is made from UV Fused Silica, a material known for its excellent optical properties, including high transparency across a wide range of wavelengths. This makes the LA4984-UV particularly suitable for use in UV applications, where high transparency is crucial. The lens also features a plano-convex geometry, with a flat front surface and a curved back surface, which helps to minimize spherical aberration and ensure optimal image quality.

The LA4984-UV is coated with Thorlabs' UV ARC coating, which is designed to enhance the lens's performance in the UV region. This coating provides broadband anti-reflection properties, reducing surface reflections and increasing the amount of light transmitted through the lens. The coating is applied to both the front and back surfaces of the lens, ensuring optimal performance from both sides.

In terms of dimensions, the lens has a thickness of 3 mm at the edge and 6.6 mm at the center. The inner and outer radii are both 0, indicating a circular shape. The effective focal length (EFL) of the lens is 200 mm, and the back focal length (BFL) is 195.5 mm.
