LB4738 UV Fused Silica Bi-Convex Lens; Dia:6 mm; f=20.0 mm Uncoated
The LB4738 UV Fused Silica Bi-Convex Lens is a high-quality optical component sourced from Thorlabs. This lens, with a diameter of 6 mm, is designed for use in a variety of applications that require precise optical control. The lens features a focal length of 20.0 mm, providing a balance between field of view and focus.
The lens is made of UV Fused Silica, a material known for its excellent optical properties, including high transparency in the ultraviolet region. This makes the LB4738 particularly suitable for applications that involve UV light. The lens is uncoated, which means it does not have any additional layers to enhance its optical properties. However, this also means that it is less susceptible to damage from environmental factors.
The geometry of the lens is spherical, with a center thickness of 3.6 mm and an edge thickness of 1.5 mm. This provides a good balance between durability and optical performance. The lens's inner and outer radii are 0, indicating a symmetrical design that can help minimize optical aberrations.
The lens's parameters are as follows: a diameter of 6 mm, a focal length of 20.0 mm, and a wavelength of 588 nm. These parameters make the LB4738 a versatile lens that can be used in a wide range of applications.
